Which is exactly the main attack I'm using, Tempest Strike. True, I was thinking on trying the Rune of Ascension.
I expected Lagon or any boss to have resistances to whatever attack genre they are using themselves, that's kinda the logical rule of thumb. But I guess not then, Shaman just sucks versus that boss, haven't had issue son any other so far. A few more levels and he's mine, was at the last phase and he had like 30% left. But my pets kept dying which give some leech on lightning, got the staff that gives 19% leech on lightning.
Nah, I kinda don't follow any guides and figure it out on my own, I play the skills I like and works (synergy wise) and I play until I don't have any more fun, like if it gets frustratingly hard. Not that fan of hard tbh, as I want to feel heroic and not some weakling that struggles.
