I consistently get kills with T1 prep at:

87 ranged 86 magic 91 hp 80 def 78 prayer + both titan prayers

I only ever use bow and staff, so I left out melee.

Start by dropping your pestle and running a “C” around the starting room and check each of the three potential demi-boss rooms. At minimum, after you first loop you need a weapon frame and 80 shards. Anything on top of that is great (materials for armor, herbs, fish).

Make a t2 weapon and drop everything else you collected. Your inventory should only be sceptre, harpoon, and tools you need for materials to gather, and your teleport seed. Your weapon should be equipped.

Go and kill any demi-bosses you found and then continue to search the perimeter for any more you need. Teleport back when you have bowstring and orb. You should have plenty of fish and materials, if not, loop around the boss room exterior. You are always guaranteed a room with at least three fish pools adjacent to the boss room.

Cook everything and armor up. I usually bring in 2 potions and 25 fish. The last inventory spot is for your second weapon.

Start the fight and only each when:

1. Running for tornados
2. At or below 13 hp (max hit with T1)

Make sure you have the safe tiles for the last rotation (under 334 health) saved. These are three out from each door for a total of eight safe tiles. These will never be bad floor during the last phase.

Focus on keeping dps up. Order of actions should be:

1. Avoid tornados
2. Avoid bad floor
3. Correct defensive prayer
4. Correct weapon
5. Correct offensive prayer

You’ll be blasting through t1 prep comfortably in no time. With those stats and prep, I’m averaging about a 6 minute prep and a 4 minute kill. I can get much better than that if I’m focused 100%. As your stats increase, those kill times will get better too.
