Hey, mages! Behold my new invention! Walk up to see it for yourself! I'm not a big fan of walking, you see. I prefer working out my brain, and not my legs! My beloved little self-propelled vehicle Tes'Lin, will get me anywhere and everywhere, spawning drones and spelling trouble for mages! I'm a damn genius!

Skills

White: Tes'Lin's Overdrive

Each attack charges Tes'Lin up by 10%. When the Charge reaches 100%, Isaac can activate her first ability: Tes'Lin emits an electromagnetic impulse, silencing all enemies for 4 seconds.

• Chance to apply debuff is lowered if the target's level is above 130

Green: MP-300 Capacitor

Tes'Lin's Magic Power Capacitor absorbs a portion of any magic damage taken by Isaac and his allies, transforming it into her Charge. The amount of Charge Tes'Lin gains is 4 times the energy allies would have received for taking that damage.

• Absorbed magic damage from Isaac: 69.282 (0.012% Health + 0.05 * Level + 10)%
• Absorbed magic damage from allies: 19.495 (0.003% Health + 0.01 * Level + 5)%

Blue: Drone Swarm

If Tes'Lin's Overdrive is activated more than once during a battle, she also spawns Drones on all subsequent activations. The Drones boost Physical attack of allies for 8 seconds. The efficiency of the boost efficiency is doubled for allied Engineers.

• Physical attack bonus: 13,696 (12% Physical attack + 10 * Level + 110)

Violet: High-Voltage Module

If Tes'Lin's Overdrive is activated more than twice during a battle, a high-voltage module is triggered on all subsequent activations, damaging all enemies.

• Damage: 120,965 (110% Physical attack + 50 * Level + 2,010)
