Repair Capsule: Instantly repairs the users Shield to 100% when activated. Icon is similar to that of the Remedy Capsule but is green instead of cyan.

Mecha Turret Kit: Drops a small turret that automatically fires at nearby enemies, (could possibly be picked up and moved once placed?). Icon would be the turret as viewed from the side.

Crystallization Kit: Creates a wall of Crystals 3 blocks wide and 1 block thick for use as cover or to block off enemies. Icon would be a wall of Crystals.

Potion of Strength: Increases the Damage and/or Attack speed of the user (T2 lasts longer than T1, T3 gives bigger bonuses than T2.) Icon would be similar to the vials but the icon would go from top-to-bottom rather than being slanted.

Potion of Defense: Increases the Defenses and/or Status resists of the user. Works same as above.

Potion of Speed: Increases the Movement speed and/or reduces the Charge Times of the user.

As for the effect I was wondering if you could replace the puffs of smoke when a player joins or leaves a group with that little "Teleporter Effect" that the NPC Recon Knights do in the rescue missions when they've opened the gate? Would look nicer I think.
