Ability Scores. Each head of the ettinling rolls unique Ability Scores.

Hit Points. The ettinling's shared total Hit Points are equal to the sum of both the Will and the Way's Hit Points.

Armor Class. Each head of the ettinling calculates its Armor Class separately. If one head is wearing armor that the other is not proficient with, the non-proficient head is treated as though it is not wearing the armor.

Combat. The ettinling is considered two targets sharing one space, and makes two separate Initiative rolls in combat. They can also choose to swap their Initiatives immediately after rolling (both heads must be willing). An attacker must specify which head it is targeting when making an attack against the ettinling. If both heads take damage from an area of effect (such as with a dynamite stick or Fireball spell), the damage is rolled only once, but each head suffers any other effects separately. If one head has the Prone, Grappled, or Restrained condition, changes size, teleports, or is moved in a direction, both heads are affected.

Death Saves. Whenever the ettinling starts its turn with 0 Hit Points, both the Will and the Way must make a Death Saving Throw. Instead of needing three successes (stable) or three failures (death), an ettinling needs to collect five of a kind.

Saving Throws. Special interactions regarding saving throws on an ettinling are detailed as following:

• As both heads think independently, all Intelligence, Wisdom, and Charisma saving throws are made individually.
• Since the ettinling shares one body, all Strength, Dexterity, and Constitution saving throws are made by the Way only. This also applies to ability checks made to end the Grappled condition, regardless of which head is affected. On a fail, both heads suffer the effects as one body.

Spells. Special interactions regarding spells and other magical effects on an ettinling are detailed as following:

• If the ettinling is targeted by a spell or other effect that would unwillingly change their shape or alter their location (such as the Polymorph or Banishment spells), both heads must make a saving throw. If either succeeds, the spell has no effect.
• If the ettinling is a willing target of a spell or other effect cast upon them, both heads may gain the benefit of the spell as though they were a single target. However, spells and effects with a duration targeting the ettinling in this manner halve the duration of their effects.
• Casting a spell targeting a willing ettinling twice (such as the Fly spell) does not double its effects, nor alter it in any way.

Wild Shape. If one head has the Wild Shape feature, their transformation has the following rules depending on whether the other head chooses to Merge or Mount:

• Merge. The ettinling shape-shifts into a two-headed version of the chosen beast. This new form has twice the Hit Points of the beast, but grants no special actions to the merged head. In this merged form, the head that shape-shifted will have control of their movement regardless of its original speed. All rules of the Wild Shape feature otherwise apply as written.
• Mount. The other head treats the Wild Shape as an independent mount following the rules of Mounted Combat, but they cannot dismount or fall off. The head that shape-shifted will have control of their movement regardless of its original speed, while the mounted head's speed is reduced to 0.

Ettinling Names

Both heads of the ettinling demand to be identified independently from the other. As such, both the Will and the Way have unique names. However, when people refer to the ettinling as one, they typically combine the names into a hyphenated bastardization of both: a compromise that both heads begrudgingly accept.

• Example Way Names: Alugvag, Clutgar, Delvog, Honsag, Jitsag, Tegir, Wugkaos, Xaldius, Zoflor
• Example Will Names: Alawver, Aozus, Carog, Domom, Glezar, Krixsag, Lubar, Mafder, Omgant, Rotos, Zlazsar
• Combined Names: Alug'Bar (Alugvag Lubar), Delv'Sag (Delvog Krixsag), Wug'Der (Wugkaos Mafder)
