I roll with 2 Purple and a Blue, simply because they are the best I have for her.
I use +shield. +shield all day, it is beautiful!
My gear load out is +shield, +shield; +shield +crit damage; +attack damage, +health. The last one I occasionally exchange for my legendary lifesteal gear, but I’ve been finding that the +health is better than 13% life steal. I think it is just that the lifesteal isn’t enough to keep me in.
Now, I use that because it is what I have. +shield, I think, is the best on her. +shield is nice, even if it is low, it is like wearing a helmet on the battlefield. Having a shield prevents you from taking random collateral damage or AOE. It also prevents random damage from stopping your lovely health regen. Any shield is nice, I prefer a big one (225). I’d like 300. Even a small shield of like 50 is useful for preventing your health regen from stopping. And, all shields look the same from the enemy. They are displayed by percentage, not total. When a foe sees you, all he sees is that you have a full shield, he doesn’t realize that it is only 50 strength haha. This may cause him to think you aren’t worth the effort/risk.
I think +health regen might be nice, too. I will maybe test +shield with +health regen. I haven’t, only because her health regen is already there, but maybe increasing it will be better than more health.
I use very expensive gear. I don’t use cheap gear with her. I can usually fund all 3 of my expensive pieces by round 3. She is decently mobile and is pretty durable on her own, so finding shards isn’t an issue. And with health regen, I liked to farm shards when my health is low.
My Mellka, by end-game, has 2k health and her shield. She wrecks it in PvP with her survivability and damage out put. Many people call Mellka squishy, I completely disagree. I think she is tough as nails. She is fast, has chaotic movement with all of her jumps and lunges, has HIGH health and damage, and all of this comes in a small frame (meaning she is a hard target for her foes).
