General overview

Arene fills a unique role among the Lords with his drone priority. He also can do Arts damage like many of his contemporaries. He doesn't do as much damage as a sniper or caster would, but he's a good pick for IS because of his low cost and ability to fill multiple niches at once.

E2? He does his job fine at E1, but for how cheap it is, you may want to get him to E2 once you have your more urgent priorities taken care of.

Talents

Arene's talent prioritizes drones and gives him a pretty hefty ATK bonus when he attacks them. Note that the drone priority only applies to his ranged attacks

Skills

he'll still attack enemies he's blocking before drones.

Masteries

S1 (Just Kidding) reduces Arene's block count to 0 and has his attacks hit twice with increased damage each time. This skill can be useful when you want him to strategically leak enemies or focus exclusively on hitting drones, as he can't block enemies and get distracted.

S2 (Deadly Prank) gives him Arts damage, an extra target, an increased attack range (caster range), and it removes the penalty he gets on his ranged attacks. The DPS on this skill is usually better than it is on S1 because of the scaling on Arts damage, extra target, and full damage with ranged attacks.

Modules

Neither of his skills get a ton out of masteries, but S2 definitely wouldn't hurt if you like to use it a lot. M3 gives him a 20% multiplier increase and reduces the SP cost by 5 seconds.
