Shik Tal is a member of The Grustrag Three. He wields a modified Marelok that fires small dumb-fire rockets (akin to those fired by Hellions) and a giant shield similar to Shield Lancers. Similar to the Shield Lancers themselves, he can use his shield to charge forward to knockdown and knockback players.
Although Shik Tal does not spawn by himself under normal circumstances, he may individually spawn inside Darvo's weekly mission as a Field Boss if the associated faction of the mission are Grineer.
Releasing the Grustrag Three? Tell me this rumor is a lie. Tell me you have not forgotten what those defects cost me. Traitors must be eradicated but you think they can be rehabilitated? Arrogance. If it was up to me, Grustrag and everything in it would be ash. No Doctor can cure disloyalty.
The responsibility for this mistake is yours alone. Trust me, you will bleed regret.
