hmm tough, you have good purple depth no doubt. Personally I find it hard to max a dupe 5* especially with how tough asc mats can be to come across. Personally I would hold ya tabards incase another 5* purple comes along. My general rule of thumb is do not max dupe 5* unless you have at least 12 of the asc mats RE tabards.
I had the choice, i went 2nd aeron. Use both in 2 different war team setups, he comes in handy. Idk how many times I’ve been relieved that hel drake gm etc have targeted the 3 immune allies
Dang, Tabards sure do like you ! So including your maxed and the ones you have you have come across 41 tabards ?! awesome.
In that case yeh I wouldn’t hesitate to max a 2nd Seshat.
If I understand your post correctly you already have Grazul maxed, is this right?
If so, Grazul gives the immunity that makes Aeron special so that is covered.
Seshat should remain among the elite fast snipers with the unique replicating minions. If you regurlarly face Guin tanks in war she should be an absolute priority as well.
