Signal Search (Gacha) & Pity

Agents and W-Engines are pulled from the Signal Search gacha using Polychromes/Master Tapes. The limited Agent banner has a soft pity that guarantees an S-Rank within 90 pulls, with a 50/50 chance it is the featured Agent (losing the 50/50 guarantees the featured one on the next S-Rank). W-Engine banners use a shorter pity of about 80 pulls at a higher featured rate.
