Metamorph

Swap between sheets and tokens: any actor can have multiple forms. This module is a must for boss phases, polymorph spells, lycanthropes, shapeshifters, doppelgangers... System agnostic, check the Tutorial tab.

It's not just a change in appearance — it's a complete new character sheet each time, with its own data and abilities. You can share health between forms or keep them fully independent.

What It Does

A HUD button on any configured token opens a form picker. Click a portrait to instantly swap the token to that form. The token's appearance (portrait, size, bars, light, vision) updates from the target actor's prototype token. HP can optionally carry over.

There are two ways to populate the picker — use either, or both together.

Two Ways to Set Up Forms

Actor Forms — hand-picked (best for boss phases)

The simplest approach. Select an actor, go to the Actors tab, click Add Set, name it, then drag actors from the left panel (or from the Foundry actor sidebar) onto the drop zone. Each set shows up as its own tile in the HUD picker.

• No filters or groups needed.
• Actors are stored directly by name — exactly what you dragged in.
• Sets are per-actor and not shared. Perfect for unique encounters: a boss with three phases, a named NPC with a transformed variant, a specific summoned form.

Filter Groups — query-based (best for druids / polymorph spells)

Define a query once, reuse it everywhere. Filters scan the world and compendiums at pick-time, so new actors that match automatically appear without re-configuring anything.

• Filters tab → define queries (actor type, field rules, sources).
• Groups tab → bundle filters into a named group.
• Actors tab → Morph Groups → assign groups to actors.

Groups are global — two druids in the party can share one "Wild Shapes" group.

Setup

Open the configuration window: scene controls toolbar → masks icon, or right-click any actor in the sidebar → Metamorph: Configure.

Actor Forms (Actors tab)

1. Click an actor in the left panel → Actors tab.
2. Set the HP on swap mode.
3. Under Actor Forms → click Add Set, name it, drag actors from the left panel into the drop zone.
4. Repeat for additional sets (e.g. Phase 1, Phase 2).

Filters tab

Filters are the building blocks for query-based groups. Each filter is a named query that finds actors matching a set of rules.

1. Click New Filter.
2. Give it a name (e.g. Druid Beasts CR≤2).
3. Choose sources (World actors, compendium packs, or both).
4. Optionally restrict by actor type (e.g. npc).
5. Add field rules — a path like system.details.cr with a value like <=2. All rules must match.
6. Save Preset. The count of matching actors appears next to the name.

Groups tab

Groups bundle filters together and appear as sections in the HUD picker.

1. Click New Group and name it.
2. Expand the group (click the chevron).
3. Use the Add existing filter dropdown, or click New Filter to create one and auto-add it in one step.

Groups are global — the same group can be assigned to multiple actors.

Morph Groups (Actors tab)

1. Click any actor in the left panel → Actors tab.
2. Under Morph Groups, check every group that actor should have access to.

That's it. The HUD button appears on the token once at least one Actor Form set or Morph Group has actors.

Swapping Forms

Select a token on the canvas and open its HUD. Click the masks icon to open the form picker.

The picker shows each group as a section. Click a portrait to swap to that form.

The token keeps its position, rotation, and elevation. Everything else (name, image, size, vision, light, bars) is replaced by the target actor's prototype token settings.
