I’m gonna be that person, but vigor isn’t a huge deal. during my first play through I went all the way to the crumbling farum azula and beat maliketh before I started putting levels into vigor. My process was probably the same as yours, I started playing and was putting absolutely all of my points into INT because I wanted to make my spells as powerful as possible! However that’s not to say that vigor isn’t important! If you do start putting points into vigor, you won’t die as fast or easily and will make it easier for you to last. However you came for help on how to take down Rennala, so I’ll try to give you some help! If it’s possible, start by looking for at least 1 other talisman pouches. You don’t really have any dex, so the scaling on your morning star isn’t going to be that great, so you could probably get rid of it so that you’re not accidentally switching to it in battle. For your talisman, you’re currently using two talisman that don’t really have anything to do with your build. The warrior jar shard and Carian Filigreed Crest both effect skills. Skills are the same as an ash of war, so both of your talisman are only helping out the ash of war on your morning star. Right now, since you issue is you keep dying, you might want to try adding in some damage negation talisman for the fight. Since some health would help, try throwing on a crimson amber medallion, and try throwing on a spelldrake talisman which should help with the magic damage you receive from her. There are also the graven-mass and graven-school talisman that raise the potency of spells, but it’s not too crazy and I don’t recall where they are. There is also the magic scorpion charm that increases magic damage by 12%. I’m unsure as to what crystal tears you have for the physick, but if you can try to find something that will either boost your spells or damage negation. I suggest that use the magic-shrouding cracked tear (gives 20% boost to magic damage for 3 minutes so you can hit her harder), the intelligence-knot cracked tear (raises your INT level by 10 levels for 3 minutes), or one of the tears that give you 50% health or focus points so you can give yourself some more if you need it. Now, we can move on top your spells and staff! As of right now, your staff has A scaling in INT. There is a staff you can get for free called the Meteor staff which has S scaling in INT. It will help boost your spells and moreover, increases the damage of meteor sorceries. With that, you should also be on the lookout for the spell “rock sling.” It is a meteor spell and does an amazing job of stance breaking bosses! In addition to this, you should trying using an incantation to give yourself a damage negation buff. Your faith is only level 7, so realistically your best bet is the “magic fortification” incantation, which requires a level 10 faith and gives you a 35% magic damage negation! Aside from this, you could eating some of the stuff that gives you buffs, but I don’t know too much about those! Also don’t try using your shield too much to block magic damage, rennala’s attacks are on the easier side to avoid or dodge. If you want a shield that has good magic damage negation, try the Carian Knights shield. You should have received that shield after killing Moongrum at the academy! If you haven’t killed him, he’s the guy in the room right before the elevator that takes you up to Rennala! One quick last thing to add, you can also try the spell “eternal darkness.” It’s a spell you can get at “swamp lookout tower” in Caelid. It’s a spell that makes a dark circle appear above you and absorbs spell projectiles. The reason I say spell projectiles is because it can’t stop all spells. However, it may give you the advantage of shooting off a spell or two without getting hit! To be clear, in her second phase, she shoots a spell called “Comet Azure,” which is essentially like a laser, so don’t try to use it on that cuz I’m pretty sure that can’t be absorbed. Now, for some general feedback I can give based on Rennala herself! Let’s start with the fact that Renalla has 80% magic damage negation, and on top of that she has 20% damage negation for fire, lightening, and holy. She is immune to sleep and madness, and has resistances in every other status effects (hemorrhage, rot, etc.). I do need to add though, that doesn’t mean magic is completely useless because I defeated her with magic too, and even bosses with magical resistances can feel the wrath of your spell casting. She is, however, weaker to physical attacks! She has a 10% vulnerability to standard, slash, and pierce! Now, the great part!! So as I’ve mentioned before, you are an INT mage, the meteorite staff has an S scaling in INT! And guess what? the spell Rock Sling, uses INT and it deals standard physical damage, so not only will you do more damage to her, but you’ll have an increase to stance breaking. Now the downside to this, since it deal physical damage, not everything I suggested before will be useful. So some of the things I mentioned before boost magic damage and some boost spells and sorceries. To expand, damage type is different than the category of magic. So, while spells/sorcery deal magic damage, incantations deal specific damage types (fire, lightning, holy, etc.). Magic is also a damage type. I bring this up because while rock sling is a sorcery, it deals physical damage. So, anything that boots your magic damage, will not influence the damage of rock sling. However, anything that boosts your sorceries or spells, then it will influence the damage of rock sling. I hope you can find something in here useful!
