Every type of item that boosts spell damage has two forms, a temporary form and a permanent form. Fire spells, for example, have Inferno items (temporary) and Combustion items (permanent). The in-game description of these items assigns them equal bonuses to damage depending on their magnitude. Superior Inferno and Superior Combustion both have in-game descriptions that state a +50% bonus to damage. However, on the ddowiki, I found this statement: "They can range from lesser to superior magnitude. The temporary ones give +15% per lvl while permanent ones give +10%. This is to make the temporary ones have some use." This means, among other things, that Superior Inferno ought to grant a +75% bonus, contrary to the in-game description. Is the statement on the ddowiki true? Or is the in-game description correct?
