I'm currently using 3* and 4* equpments, and im using weapons that from what i see, works in every situation. Since i can't really afford 4 weapon slots yet for each damage type. i choose CIV over levi cause it has safer knockback power on party runs, and the fact that my charge attack can hit enemy multiple times before knocking the enemy back.. e.g. i can it a lumber 3 times with a charged attack from its behind, if not, 2 times. And my blackhawk is just a spot-filler till i get my pulsar.
So, here's my equips:
-dusker set
-wise owlite shield
-Cold Iron Carver
-Blackhawk
Im currently planning to get vog cub and skolver combined, grey owlite, barb thorn shield, GF, DA, CIV, Polaris, Blitz needle And maybe sentenza and ap for end game. I already prepared the recipes and mats for these equipments.
Any suggestion and tips on what weapon i should choose for end game?
Well you are including all the popular gear so it should work. I see lack of support gear (besides possibly polaris). I'm not saying you need it, but you'll have to find players that use that gear in order to have an easier time. Support gear is usually poison and freeze, but shock, fire and pure crowd control (nitronome, vortex, etc) help as well.
For the current endgame = vanaduke your usual loadout will be Owlite, vog, DA, CIV, Polaris, Blitz, and you can replace owlite with swiftstrike if you end up liking the role of blitz. Once you run vanaduke enough times you'll earn Fang of Vog which is all you need for Jelly King and Twins. For Snarbolax you can use anything. So technically you dont need Barb or GF, a shadow shield is a godsend on devilite levels, you can earn blackened crest for free.
