Once all of them detonate, or after 15 seconds, the Ally's normal form returns.
When activated, instead of the Ally's damage buff, the Ally turns into 5 smaller Allies, each exploding for 480% damage as Fire.
Fire Ally: damage type changes to Fire, the Ally's attack becomes a piercing short burst (so it hits all enemies in an 18-yard line, similar to Deadly Reach), and also increases the Monk's damage by 10% (not multiplicative to similar modifiers). Enemies hit by the wave are Frozen for 3 seconds. When activated, instead of damage buff, the Ally transforms into crushing wave for up to 15 seconds, dealing up to 7 attacks for 625% damage as Cold each. Water Ally: damage type changes to Cold, and attacks Chill enemies for 2 seconds, slowing them by 60%.
