As someone who has beaten all 3 of the console/mobile exclusive bosses, I can proudly say I am HYPED! Also, if you have not already worked on their drops, I have an idea for some unique Lepus weapons. I won't give an idea for a ranged weapon because he already has the egg cannon.
Diseaster Staff: Summon weapon, summons a diseaster bunny to fight for you.
Eggscalibur: Melee weapon, occasionally fires out an egg.
Egg: Thrown weapon, need I say more?
Staff of the Bunny: Magic weapon, fires an egg that shatters into smaller pieces, dealing 1/2 as much damage as the original blast.
