HP Charm III
Boosts Max HP by +70%. The largest percentages on any Charm, and the only line that more than doubles between tiers II and III. Charms are equipped on Koo, and the five lines — HP, ATK, DEF, Skill and Critical — each run I, II and III. Each charm also carries one rolled mod, named and levelled, which is why two charms of the same tier are not the same item.

When to use it
The top of the Max HP line at +70%. A five-by-three grid with published values is exactly the "citable name, tier and value" this site once recorded as not existing for Charms, which is why the catalogue's own note says so. What is still not published is which Charm drops where — no source gives a location for a single one of the fifteen.
Where it sits in the gear catalogue
- The three Max HP charms run +20%, +40% and +70%, and this is rung 3 of 3: HP Charm I and HP Charm II are the same effect at a different size.
- Charm percentages are not comparable across stats, which is the trap this ladder sets. The top rungs are Max HP +70%, Attack +7%, Defense +70%, Skill Power +20%, Critical Rate +8%, so a "+70%" and a "+8%" are ceilings on different quantities rather than one being nine times the other.
