Botanical Tunnelers were Bio Lieutenants native to the planet Verdanth . They were large, plant-like enemies with large teeth-like spikes. Despite their numerous "teeth", Botanical Tunnelers only attacked by burrowing through the ground and ambushing players with AoE poison clouds.
There were three Botanical Tunneler Captains in the game, one in each difficulty mode:
- Contagion, the Deadly Epidemic (Onslaught)
- Cormeer, the Cloud of Death (Invasion)
- Tunax, the Toxic Terror (Apocalypse)
One of the most destructive Darkspore entities on Verdanth is the terrifying botanical tunneler. Burrowing through soil, sand or even solid rock, a botanical tunneler can surprise even its most uncanny enemies by erupting directly next to them. Protected by an iron-strong dendritic armor, a tunneler kills with its toxic death cloud that can penetrate most armor types.
They were completely immune to attacks while underground, and would remain motionless while above ground. If the player moved far enough away, they would return into the ground and pursue them.
Another possibility was to use Revenant's Terrifying Curse squad ability to neutralize and damage them before they had a chance to dig.
If you happened to get poisoned, you could cure it with Meditron's Syndrome Shift or Tork's Sporogenisis, just to get it out of the way. A word of caution with using Tork though, the Tunneler's poison cloud would automatically Crit because they were both Bio-genesis.
The 'Immune to being poisoned by Darkspore' secondary stat would render Botanical Tunnelers completely harmless, the only exception being their melee attack from bursting out of the ground.
- If a Botanical Tunneler tunnelled beneath an energy bridge on Zelem's Nexus, the player could see them underground before they even emerge.
- Botanical Tunnelers beared a resemblance to 'Leevers', common enemies from The Legend of Zelda universe.
- Botanical Tunnelers also (somewhat) resembled the real-life Trifolium repens, otherwise known as the 'White Clover'.
- Due to their peculiar body structure, it was hard to discern where the front or back of the creature was, making Skar's Opportunism almost useless against them. However, as with most enemies, they would likely face you to attack, so this could be used to get a general idea of which direction its facing.
