Omegorb

Omegorb is an orb that trades immediate power and Overflow for a harmful effect on later shots: it upgrades pegs while also causing subsequent pegs to be worse. That makes it a classic risk-versus-reward option, and it works best when its downside is offset rather than left to snowball. Its mechanic is similar to Endless DevouRing.

Because Omegorb can weaken future peg values, it benefits from effects that restore or improve pegs. Swoltorb and Reforbisher both help offset the damage loss it creates, and Level 3 Swaltorb and Reforbisher at all levels can outperform Omegorb as peg-upgrading tools. Glorious SuffeRing is especially notable with it: at Level 1, Omegorb plus Glorious SuffeRing becomes a stronger version of a Level 1 Swaltorb while also adding Overflow. At Level 2 and above, Omegorb effectively loses its upgrade and downgrade behavior and becomes a strong Overflow orb instead, so the level you leave it at matters a great deal.

• Avoid pairing Omegorb with Multiball or Morbid unless you are certain the run can absorb the downside; those effects can magnify the harm very quickly.
• If you want Omegorb mainly for its raw power, keeping it at the right level is important, since its behavior changes significantly at higher levels.
• Its name is a portmanteau of “omega” and “orb.”

Omegorb was introduced in v0.5.56. In v0.7.16, its Level 3 peg debuff was reduced from -3 to -2.
