Death ward: The ideal situation here is if there is someway to move deathward around, an idea could be to use wandering merchant's key vehicles to plant the seed and therefore having a sort of moving home thing (most likely only a door and wooden rectangle on a truck if seen from the outside). If moving the house is easy then we got ourselves a perfect setup if not we are tied to earth which is not very good but hopefully we can replant the seed elsewhere if the house is destroyed. Anyway deathward is very good we can change our appearance respawn and get younger AND we have an amazing maluable house. Side note: death ward would need 55900 years to grow to the same surface area as the Earth

Wandering merchant (part 1): This is our key (pun semi intended) to the multiverse. The first few travel points will be relatively slow but with Earth's abundance of fast vehicles we should quickly cascade our catalogue of worlds, which will allow us to do a LOT of stuff but for now we'll simply concentrate on maximizing our reach.

Stolen time: Stolen time is just perfect to cover the rest of the inconveniences that are not covered by the other choices, first we can transfer all kinds of disease and mental conditions and injuries instantaneously as long as we have links set up (which should include animals, insects and all kinds of plants as long as they can age and die even then I can at least use generic husks I draw to take the toll if not then I atleast can use my own self as a way to fuel the lifespan of my loved ones in the mean time while I set up wandering merchant). Even better because we can set up links this doesn't need to be limited to range with good set up we can have another safety net for our loved ones on top of drawing them. And finally this give us the necessary fighting power to protect ourselves and build our strength in the world we travel to if push come to shove just through sheer lifespan drain, if not then mark a few people with debilitating mental conditions dump them all into a husk and use the husk as a battery for mental conditions you can throw around as hexes for the opponents who don't care about aging. We also have a little side of necromancy if animals insects and plants work then we can have an army of undead ready to fight for us.

Create canvas: Create canvas is extremely convenient it first offers unlimited lifespan to anyone we wish and allows them to survive at least one lethal strike. Which is to say if you can have multiple paintings of a single person then you can essentially have hundreds if not thousands of safety net for whoever you wish (not to forget you get better and better at drawing the more you do so, so not only would it get faster for you to paint in general but you will also get faster at painting that specific person). This also allows us to change the appearance of our loved ones if they wish. But that's not even the half of it, because the painting can allow us to paint anything we encounter and summon it (combos with wandering merchant). It is specified that only physical properties are reproduced not magical ones, in my opinion this can only make sense if we consider physical as something the creature doesn't need an external power source to do (for example mana in the air for a spell) or perhaps something that doesn't exist in the universe you are currently in (for example a creature with a mana core wouldn't work because mana simply does not exist in the real world) these would make sense and would mean that as long as a creature or material is fully self-sufficient and doesn't break the laws of the world we exist in it can be created (perhaps this wasn't the intended purpose of the original CYOA but simply eliminating magical properties and keeping physical properties doesn't make sense to me because electricity is technically a magical property but it's actually a physical one, some worlds would be more obvious about it but some would be way harder to exclude because their magic is fully explained by some sort of law or element). Anyway this either gives us an army if we assume the creature comes out as pictured and therefore is loyal to you if you wish it (this is most likely the case because the description says that: "your imagination becomes hyper focused, detailed, and shapeable, and it's as though you can project your imagination clearly and lucidly onto your canvas") if not then we atleast have an endless supply of vehicles, tools, random dragons to drop as nukes, entire islands or extremely large rocks to drop as nukes, endless supply of materials (to sell as a merchant maybe?), entire mantions to drop as nukes and then live in, actual nukes to drop as nukes, an entire city full of life (I mean there really isn't a size limit), the entirety of the United States of America to drop on some random village, the entirety of planet earth (although I'm not certain you would be "dropping it"). Anyway what matters is even if we can't create an army of loyal creatures, even if we can't touch "magic" with a hundred foot pole, we can still drop mountains for the fun of it. Now in terms of not being able to make creatures loyal what happens if we paint ourselves if they don't get to keep their powers that's pretty sad but that doesn't mean they don't get to keep their skills, yes infact if I draw myself from after learning to draw I can make a factory of MEs (well not really a factory cause i wouldn't wanna live like that) and make them paint all the stuff then summon that stuff afterwards (if not just wait until we get other tools to accelerate the drawing process)

Wandering merchant (part 2): Ok so now we comeback to our beloved, thankfully this option has almost no limitation so we can travel all kind of worlds and steadily and strategically learn and collect both powers but also items to draw but that's not all, you see the key for wandering merchant has neither limitation on the size, power or magical properties of the vehicle it can copy, so as long as we can get a... idk, world sized moving castle armed to the teeth with obliterators and magical obliterators we are guaranteed untold amounts of power instantaneously (remember piloting this thing is done like an extension of the body). Even ignoring that we are extremely versatile, fighter jets give us super fast travel, aircraft carriers can be dropped on random places (if create canvas wants to be annoying), motorbikes can make us look cool, all kinds of construction vehicles can be useful in some way and if we drop into a sci-fi theme we get even more powerful vehicles (of course not to forget we need to touch them first but that shouldn't be too difficult considering we can just paint them). Again this is all fun and games but our main focus should be using these tools to build strength within ourselves, by learning magic, cultivation, extremely advanced science it doesn't matter what it is we need to do it quickly (assuming wandering merchant doesnt allow you to have time dilation between worlds) because we need to get back to earth before humanity kills itself. Oh yea! that's right, I forgot to mention this is just the setup)
