Arcane abilities

Arcane secondary abilities affect the use of most aether skills.

Min. Tier	Type	Ability	Milestones
1	% Elemental dmg	Increase damage of fire,water/ice,earth and air-based skills	Arcanist Aetherist Solid Aethershaper
2	% Conservation	Reduce aether costs of all skills to 1/(1+%) (i.e. 100% conservation reduces only by ½)	Planner Imposing Spotter Calculating Tactician Careful Tactician Precise Assistant Masterful Watchman
3	% Elemental skills economy	Reduce costs of elemental skills to 1/(1+%) (i.e. 100% economy reduces only by ½)	Massive Aethershaper
4	% Earth dmg	Increase the damage done by earth-based skills	Resilient Spellwrangler
4	% Ice dmg	Increase the damage done by water/ice-based skills	Resilient Spellwrangler
5	% Aether dmg	Increase the damage done by aether skills	Indomitable Spellbringer
6	% Fire dmg	Increase the damage done by fire-based skills	Teaching Spellthrower
?	% Lightning skills economy	Reduce costs of lightning skills to 1/(1+%) (i.e. 100% economy reduces only by ½)	?

1. economy and conservation abilities apply in sequence (i.e. an aether cost of a lightning skill would be reduced to 1/(1+eco%)/(1+cons%) ).
2. all damage % that apply to a skill are added (i.e. if you have 20% elemental damage, 30% aether damage, and 15% earth dmg, then earth skills do 65% more damage, not 1.20×1.3×1.15 = 1.794).
