The Alchemist

was thinking maybe you could add like:

Armor coat: Consumes mineral ores to shield the user. (the first ore in the etc would be used, this includes all non-jewel ores, as well as lidium (orihalcon, silver, adamantium, steel, gold, bronze)
Level 1: 10 mp, Consumes 1 ore, Gains 30 weapon defence, 15 magic defence, and 1% resistance to all elements for 60 seconds.

Level 10: 22 mp, Consumes 2 ores, Gains 60 weapon defence, 30 magic defence, and 5% resistance to all elements for 120 seconds.

Level 20: 34 mp, Consumes 3 ores, Gains 120 weapon defence, 60 magic defence, and 10% resistance to all elements for 180 seconds.

It would be a 1st job buff. The buff in itself is somewhat useful at all levels,and even from the start. The defence is more useful in the early game, and the elemental resistance makes the skill worthwhile in later jobs, even to 4th. I think it follows the "alchemist" job title well, and may raise the worth of some ores a bit, while not being overly expensive or cumbersome.

I like the idea, I might even use this with the stats tweaked a bit but I will give all credit to you. A skill that could partner with this might be something called Mining that would increase the drop rate of ores.
