These will have 10% of the Druid's MaxHP.
You'll get a pet bar for these which allows you to control them.
They scale with haste, crit, spell power etc. but with 10% HP scaling they're kinda weak and easy to kill.
Also their base damage / healing is kinda low but this can add up depending on how many Treants you summon.
From what I've read this talent is a spell with 3 charges, a 20s CD per charge and a 15s uptime per Treant.
Using a charge doesn't trigger nor be blocked by the GCD. So all Treants can be summoned instantly by using a macro.
1 charge = 1 treant with different looking treants for all specs as well as custom spells for them.
All treants have a base attack speed of 2 sec for their auto attacks (some don't use auto attacks).
