Expanded Sentries/Crystal Orbit

The Crystal Orbit is a Hardmode trap sentry weapon. Of note the orbiting crystal only causes 5 frames of enemy immunity hit. It has a 25% chance of being dropped by a Hallowed Mimic. Its best Modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the sentry's damage. Additionally, sentries cannot deal critical hits under normal circumstances. The only significant advantage a Mythical Crystal Orbit has over a Ruthless one is knockback.
