There are many options for fast heals in Chapter 3. Chug splashes may be the quickest and most economical way to heal your team as they heal anyone in the splash area. There's also the shield keg which was introduced in Chapter 3, Season 1. The shield keg heals anyone in its fairly large AOE, although, as its name implies, it only provides up to 100 shield. Other decent options for heals are fish, first aid kits, shield potions, guzzle juice, or fruits and vegetables. Environmental heals include fireplaces, chug barrels, and chug trucks.
