Rocky supports are huge pillars made of rocks. There are a total of three, which players can use as a safespot in the Inferno.
Each support starts with 255 health. Jal-Nibs, which appear from waves 1 to 66, will focus on attacking the supports as soon as they spawn, inflicting miniscule damage to it. The support will change in appearance and examine for every 25% of its health lost. When it reaches 0 health, it collapses, dealing damage to all monsters and players near it when it occurs. The supports automatically collapse after wave 66 has been cleared regardless of their health.
