You win one you lose one.
you lose a big one you gain a small one 
There is more of a loss than a gain (but making it based on the destruction stat doesn’t really buff heat based magics aside from explosion).
yeah i cant wait to be fighting on my boat and the enemy just jumps in the water and theres nothing i can do about it but i will burn there boat down no matter the cost
Plasma actually has pretty good destruction.
Fire…
Fire too but to a lesser extent.
There’s things fire can do that plasma can’t. For instance, fire synergizes better with ash.
aye dont do my fire like that…
-cries in ice magic doesn’t work underwater-
neither does any heat based magic 
i totally forgot about ice, and my second account is ice too…
Yeah Plasma’s Destruction x Damage is 25% higher than average, and with Scorch that’s really gonna help.
It’s going to be Verdies vs Trigno all over again. Minus Argest.
