Replace aura on spirit of barbs

[Anu-11792]

Keep it thorns as it’s name indicates

But give it its own thorn type

@Anu-11792

Skill: spirit of barbs

Skill flaw: reflected damage has never been in a good place to begin with and this one is easily outshined by how strong oak sage is

Skill change:

• now returns damage based on a % of the person that gets hit’s total life
• regardless of damage source or type. Which means it can be melee or range or phys or magic or cold
• the spirit barbs don’t affect himself, he don’t return damage
• the damage returned is the same damage type as well
• when killed there is a 15sec cooldown before being able to respawn it ( for Pvp balance)

• Let’s say for example it returns 10%* at level 20 and your bear has 10000life and gets hit, the damage returned will be 1000

This could be a solid option to improve Druid summoner which would create an alternative to oak sage and hearth of wolverine
