Rarity
Mage

1) Ruby For Vigour
Throws a ruby in a line, damaging the fist target hit.
Gemfinder effect: Adds fire damage-over-time upon hit.

2) Emerald For Insight
Reveals a target area, including anypony in it.
Gemfinder effect: Also reveals stealthed targets and wards.

3) Sapphire For Divinity
Drops a sapphire from the sky, creating a small area of effect damage.
Gemfinder effect: Increases the area of effect radius and adds a slow effect.

4) Opal For Harmony
Request help from Opal, Rarity's cat. Opal reluctantly claws at nearby targets and minions, and remains until defeat or until duration expires. Opal gains a % of Rarity's stats.
Gemfinder effect: Instead of summoning Opal, Rarity makes all allied Equestrians in range immune to all damage and crowd control for 2 seconds. Allies must remain within her radius to gain the effect.

Rarity herself is not affected by the immunity, and is unable to move, attack, use abilities or items for the duration. Hard crowd control such as stun, knockback and knockup, as well as Rarity's defeat, will prematurely end the ability.

P) Multitasker: Gemfinder
Always active, this ability allows Rarity to spot hidden gems when nearby. Rubies, Emeralds, Sapphires and Opals can be collected. Rarity can carry a maximum of 3 per gem type, 1 gem is consumed upon next use of the matching ability, adding a Gemfinder effect. Opals are the most rare gems and harder to find. Only Rarity can spot these gems, although a matching colour effect is visible for all within visual range whenever Rarity picks up a gem.

Multitasker: Swift Tailor
Defense debuffs last 2 seconds shorter on Rarity and nearby allies within range, due to her passive repair of defenses.
