Savants are going to have the highest attack size in the game too, which is all the more reasons to hate them.
An explosion-imbued dense lion’s halberd/lance of loyalty is going to have a base size affinity of 2.209, pair that with the equipment that results in the highest attack size possible (629) and you’re getting projectiles with 4.115× the base size (post-affinity, I think. I used Affinity×(AttackSize%/100+1) and I don’t know if it’s right). That’s a striking gale with a size of 88.53 (post-tier calculation), 115.09 if fully charged.
Size comparison (if measurements are in studs and the math right)
Note that I did not account for the added weight of colossal cleaver weapons, so it should be a bit bigger.
Not actually though, sailords will be getting 4.271× the base size and a tiny bit more tier scaling, resulting in a striking gale of 92.57 size, 120.34 if fully charged.
