Question about shadow warrior's nether allegiance combat art

[flamechamp 0]

I know there is a shadow warrior section, but questions get answered fast here.

 

Basically, I'm a level 34 shadow warrior and my nether allegiance combat art says the regeneration time/cooldown is like 70 seconds or close to that, but for some reason, I can summon the skeletons, desummon them & make them explode, then resummon them, an infinite amount of time, without having to worry about regeneration time/cooldowns. What is up with this? Isn't it supposed to take like 70 seconds before I can use the nether allegiance combat art again?

 

I think my astral lord focus is at 22 and my astral lord lore at 17 and I have memorized 9 runes for nether allegiance, so my nether allegiance level is currently at 9 or 10.

I believe what you are looking at is the regen penalty for other Combat Arts. Buffs can be activated and de-activated without any cooldowns
