Frisk/Enemy

Frisk is one of the two enemies in Bonetale, alongside Chara. Their behavior varies among the different difficulty levels in the game.

Easy
Frisk is relatively slow and weak, cannot dodge any attacks, and can't heal with items. Their speed progressively becomes faster as the levels get harder, and this is shared amongst all levels. Frisk will flee from Undyne's Green SOUL mode and Sans's Gaster Blaster attack. On Easy 2 and 3, they will jump when in Blue SOUL mode.

If they have litte HP, they will get tired and run to the opposite end of the map. In this tired state, they will stay still unless approached, but they will not attack.

If they are Knocked Back to a map's edge, there is a slight chance that they will become dizzy and be stunned for a short time.

Medium
Medium Frisk becomes a bit faster and stronger, and will occasionally dodge attacks, most notably, White Bones. They can now heal, once at Medium 2, and two times at Medium 3. Their attack speed increases. Like Easy Frisk, they get faster as the levels get harder. Frisk will not flee from the Gaster Blaster (instead tries to dodge it), but will still run from the Green SOUL change. They jump more frequently in Blue SOUL mode.

Similar to Easy, Frisk will get tired if they have little HP.

Until Medium 2, they are Knocked Back to a map's edge, there is a slight chance that they will become dizzy and be stunned for a short time.

Hard
Hard Frisk is quite fast and powerful, and will attempt to dodge most (if not all) attacks. They have an insane attack speed, can also heal, max three times, and will relentlessly jump in Blue SOUL mode.

Frisk does NOT get dizzy or get tired, even with little HP, and will continue to pursue the player character no matter what.

Their most unique ability is the power to turn into Chara.

Chara
Chara has three phases, the base (Phase 1), and the two others, often dubbed Phase 2 and Phase 3.

Phase 1 Chara can be seen on all Hard and UnderFell event levels, Demonic, and is similar to Hard Frisk, but they will DESTROY all Bone attacks except for the Blue ones and the Traps. They can also kill the player in one hit.

Phase 2, can be encountered from Hard 2 onwards. They are similar to Phase 1, but will dodge all attacks.

Phase 3, Chara's final phase, is encountered only on Hard 3 and Demonic. They have a monstrous attack, attack speed (which can only be truly observed as Undyne the Undying, at eight strikes per second), and walking speed, so much so that they could easily catch you off-guard if you're not careful. They will destroy every bone attack including the Bone Trap (except the Blue Bone and Trap, which cannot be destroyed). Phase 3 will attempt to reach you even in Blue SOUL mode, which occasionally leads into a bug that sends them flying towards you.
