There appears to be an error in this node, but forgive me if I’m reading it incorrectly.
Speccing out a new build I noticed in the Flame Rush tree when looking at the Magma Starter node that it states “The effect consumes mana equal to a portion of Volcanic Orb’s mana cost”, but at the bottom it shows “Volcanic Orb Mana Consumption: 110%” which seems to contradict the first statement.
A “portion” means part of the whole, but 110% is more than the whole.
