Single Target spell. Cost 25 Mana
When cast on a target, it will place a protective psi shield on the target that can absorb 25 damage. The target will be immobile for the duration of entomb and the target will not be usable, sort of like a stasis field, but the shield can be destroyed. The target can be ANYTHING physical on the map, i.e, mineral patches, your own units and buildings, enemy units and buildings, widow mine missiles, infested terrans, broodlings, locust, and even destructible rocks. The target would be free after the shield has been destroyed or timed out.
Ideas on how it could be used:
Harass: Cast on enemy mineral lines to prevent mining, Cast on enemy workers to prevent building mining scouting etc, Cast on destructible rocks to deny expansions.
Defensive: Cast on that one single immortal when its being targeted by a ton of roaches, cast on a building to prevent it from being sniped, could also be cast on medivacs or mutalisks to prevent them from escaping.
Offensive: Cast it key enemy units to delay attack or cause a change in positioning, could be cast on siege tanks to render them in effective in a certain push.
