Item School: The School of magic that a magical ingredient falls under, some may fall under multiple.
Item Categories: Categories that specify what the crafting ingredient can do within its school. Like schools, a single ingredient can have multiple categories.
Item Tiers: The power and quality of an ingredient.

Item tiers scale from tier 1 to tier 8, with each tier having larger maximums than the last. Utilizing higher tier materials at lower stats (range, damage, AOE, etc) leads to lower DC's, while moving closer to the tier maximums leads to higher DC's.
Note that any statistic of any item will never surpass its highest level component.
The maximums for each Tier goes as follows:
(Tier 1) 1d6 damage, 10ft Range, No AOE, No Status
(Tier 2) 2d6 damage, 30ft Range, 5ft AOE, 1 Status
(Tier 3) 3d8 damage, 50ft Range, 10ft AOE, 1 Status
(Tier 4) 4d8 damage, 70ft Range, 15ft AOE, 2 Status
