Welcome all!
I want to suggest a skill, but you shouldn't take it as a serious suggestion, because this skill will put a huge load on the game due to the heap of animation.
The idea is taken from the game Hots from the hero Rexxar.
Skill name: Onslaught of Mountains.
You summon mountain boars to help them run towards the target and deal damage on impact and damage along the way.
Cooldown: 40 seconds.
Cast range: 5 cells.
Damage that the boar deals along the way: 15% of physical strength.
Damage on collision with a target: 25% of physical strength.
You summon 1 \ 2 \ 3 \ 4 Boar in turn (the interval between the appearance of boars is 2 seconds).
