Pyroclast Mine

Fire Nova Mine is a mine skill. When detonated, this mine creates a series of novas, each one dealing higher fire damage than the previous.

Skill Functions and Interactions

Detonation - The mine is not destroyed immediately on detonating and needs to be alive for additional novas to be cast. The mine can be killed during this time and prevents further novas.

Casting Speed - Fire Nova Mine is one of the only mines that is heavily influenced by player casting speed. As with all traps/mines/totems, Fire Nova Mine uses the casting speed and other stats of the player that placed the mine when it casts its skill. This means that the higher the casting speed modifier that the player has, the shorter the amount of time it takes for Fire Nova Mine to repeat its casts. This makes the support gem Faster Casting SupportFaster Casting SupportSupport, Spell

Additional Effects From 1-20% Quality:
Supported Skills have (0.5-10)% increased Cast SpeedThis is a Support Gem. It does not grant a bonus to your character, but to skills in sockets connected to it. Place into an item socket connected to a socket containing the Skill Gem you wish to augment. Right click to remove from a socket. a very useful support gem as it causes Fire Nova Mine to hit targets within its specified range with the repeated Nova casts faster, and lowers the potential for enemies to escape the area between Nova casts.

Damage - The tooltip of Fire Nova Mine only shows it's base damage and it's actual damage is a lot higher. To get the actual damage of a Level 20 Fire Nova Mine, multiply the tooltip by 5.8 (1+1.3+1.6+1.9) for the base skill and 10.5 with the +2 repeats enchantment (1+1.3+1.6+1.9+2.2+2.5).
