- I intentionally didn't put in damage + mana + stats numbers because I am not sure what would be appropriate
- Level 16 Melting Onslaught Talent's damage + Black Fire with Level 4 Square Blaze Talent's effect can overlap. Together with Level 20 Miraculous Chains it can be pain in the *** for an enemy standing in the middle of the five blasts, after completing the Level 1 talent Endless Blast
