Holgar throws 2 axes by default, if you equip trident, he will throw 4.
Lucifer's attacks chain, so with trident, he will do 3 attacks that all chain.
And with the Lucy buff (which i had in mind) he can hit 4.
Holgar then can hit 1 creep with 2 axes and 2 additional ones with 1 axe each?
Because i think i saw him not split the attack. But it is long ago so I might be wrong.
