Cookie Run: Kingdom's Hall of Ancient Heroes allows you to match Disciple Cookies' levels with Paragon Cookies. This will boost the Disciple Cookies' levels but doesn't actually level them up. Once removed from the Hall of Ancient Heroes, Disciple Cookies will revert back to their original levels. Despite this limitation, you may find this Hall to be extremely convenient for helping newly-pulled Cookies catch up with the rest of the team within minutes.
How do Paragon Cookies Help Disciple Cookies in Cookie Run: Kingdom
You are required to have five Cookies on the pillars of the Hall of Ancient Heroes. The lowest-leveled Cookie among them will be the Paragon Cookie, whose level will be projected onto all Disciple Cookies. If the Paragon Cookie's level increases, the Disciple Cookies' levels will also be boosted to match.
Meanwhile, Disciple Cookies need to be a minimum of level 30 to participate. They are boosted free of charge, and they can occupy a slot forever. However, once you remove a Disciple Cookie from a slot, you need to wait five days for the slot to open up again. More slots can be unlocked using Radiant Shards.
How Do Boosted Disciple Cookies Work in Cookie Run: Kingdom
Boosted levels are not permanent. Disciple Cookies will only remain boosted as long as they stay in the Hall of Ancient Heroes. Once removed, they will revert back to their original levels. When you level them up using EXP Star Jellies and go above the Paragon Cookie's level, Disciple Cookies will maintain their original level, even while in the Hall.
Can you play with Disciple Cookies?
Disciple Cookies can be used anywhere, whether for producing materials or battling enemies in World Exploration, the Arena, and more. Putting Cookies in the Hall doesn't make them unuseable—the same applies to the Paragon Cookies and the others on the pillars. When using Disciple Cookies, they will be at their boosted levels. Their stats will naturally increase to match the boost.
What happens when you upgrade Disciple Cookies' Skill levels?
In CRK, Skills can only level up to match the Cookie's level. You can level up the Disciple Cookie's Skill to match their boosted level. Once removed from the Hall of Ancient Heroes, their Skill will revert to match their original level. However, the upgrade function will be locked until you match the Skill level upgrade during your boosted era. This means that you can safely level up Disciple Cookies' Skills without worrying about spending twice on Powders.
