How it works

Calvin Ball is a companion: an Eye of Ender that follows you, fights beside you, and snatches shots aimed at you. Hold the head of Calvin_Rhodes and right-click the eyed end portal frame at the centre of the bedrock seal. The head is spent, the frame gives up its eye, and Calvin Ball wakes. Calvin Ball wakes and takes your side.

• It strikes hostile mobs within 12 blocks of it, twice a second.
• It has 40 health and slowly heals itself.
• You keep one Calvin Ball at a time.

The drawing stays. Set a new eye in the frame to wake another after yours is gone.

Good to know

Do not taunt the Calvin Ball. Strike it, and it turns on you for a few seconds.

A Tier 2 or higher Dispel dismisses it.

Configuration

Setting	Default	What it does
attack-interval	10	Game ticks between companion attacks.
heal-interval	100	Game ticks between companion heal pulses.
max-health	40	Companion health. The visual is not a living entity; this is plugin-owned.

heal-amount	1	Health restored on each companion heal pulse.
hostile-search	12	How far the companion looks for hostiles, in blocks.
