Odin starts with 3 buffs.And now I can't think of the multitude of others 🤣😅
Gladiator and Vox have vigilance on their sp2s. Vox also gains a lot of unique buffs pretty easily. Surfer sp1 has a vigilance + he can gain 3 unique buffs (4 if you count the dex buff, 5 with the vigilance itself).Deathless/regular king groot, galan, angela, odin, medusa, hyperion, sersi, ikaris, and venompool should also be able to stack a good few buffs. I know it says unique buffs on the node, but even 1 type of buff is enough to get the vigilance up most of the time. You can even pair up relics to give you extra buffs like the thor/gamora/cap marvel relics. It wasn't too bad.
