Glass cannons very similar to Mantis in stats and skills, though with a few notable differences which means the Tansect must be used more strategically.
Tansects don't have an option to initiate without using AP, like the Mantis do with their LongJump. However their natural jumping movement combined with Agile means they generally get around much better than Mantis do, giving more opportunities to pierce and Slice.
Their BulbJump, unlike other jumping skills, isn't meant for initiating but for spawning a SlimeBulb near the frontlines. While that has a long cooldown, the fact that the Tansect has SlimeTrail onMove means having a Tansect makes it easier get slime to use in the frontline, though due to their jumping movement it's not ideal for terraforming.
When jumping, they can inject a bulbseed into the ground.
