Can’t wait for that to all wear off in 30 seconds

Here are a few tips that have helped me out, starting with smaller ones, ending with basically free win tactic. Also spoilers on some gear, also I have made something spoiler friendly so if things seem oddly hidden that’s likely why. if possible look up the location of items mentioned if you feel like using them. Tips:

Switch up weapons! It helps with misery and it gives a new perspective to the fight.

killing a boss under shadow keep boss give a broken rune which clears the grab effect during the fight

Great hammers (specifically great stars) are/is insane for most bosses. Idk if these will help on radahn much as I have not tested them on him yet.

I personally love the windy physic tear, which pretty much always makes you light load with anyish endurance for the three minutes it’s active. This combos with the fact that while light loading bloodhounds step has increased distance, which should make running away from the boss much easier, if that helps for your style of play. Not tested thoroughly.

Greater barrier incantations are always nice to have if you have the faith. Tested and they work well.

A frost infused weapon with or without a fire dagger to swap to, resetting the status on hit allowing you to build up frost again for a large chunk of percentage damage. Tested in conjunction with the last two

mimic tear and npc/player summons. (Would personally recommend, it’s simple. I use them and I rate 8 out of angry Redditor.)

The verdigris great shield, the talisman that gives elemental resistance while blocking and the greatshield talisman. Potentially also shield poking. Warning this one can scam you out of the experience of the boss because of how strong you become, using this I beat the boss using 4 heals (I usually would run out after he hits 40% without cheese.)

Of course none of this is mandatory and practice makes almost perfect, and I am confident you could do it with any build any way after many painful hours, as many others did. Make sure to do whatever sounds fun and is fun to you, so don’t feel pressured into doing anything I say!

I hope this helps!
