Skills & Abilities
Monsterion has two parallel skill systems: the per-leader active/passive skills (RTS heritage) and the universal mobile MOBA abilities (built for touch).
Per-leader active skills
Named active skills attached to specific leaders via scene instancing:
| Skill | Leader |
|---|---|
| Aura of Courage | Arthur |
| Guard Break | Arthur |
| Critical Slash | Bokuden |
| Multishot | Robin |
| Trader | Osman |
Skills are attached to a unit's behavior/abilities node in the leader scene. Passive
skills (e.g. cleave AOE, pierce armor-penetration) are wired through the behavior /
modifier system.
Known gap: several named skills in
active_skills.gd(Guard Break, Cleave, Dash, Battle Call, …) have emptyeffects: []arrays, so on the desktop build they enter cooldown but run no effect. Many leaders have no per-leader skill entries at all. This is the main reason the mobile build uses a universal ability set instead.
Universal MOBA abilities (mobile)
On the mobile/web build, every leader gets the same three self-contained abilities — they don't depend on the per-leader skill dict, so they work for the whole roster.
| Ability | Icon | Effect | Cooldown |
|---|---|---|---|
| Sprint | Lightning (blue) | +50 speed for 4 s | 8 s |
| Battle Cry | Sword (purple) | +25 damage for 5 s | 12 s |
| Heal | Plus / star (green) | Instant +200 HP | 10 s |
Implementation notes:
- Effects ride the
Behavior.modifiersadd/remove system with a stable mod name ("moba_skill"), so re-pressing mid-duration is stack-safe (the previous modifier is removed first). - The cooldown countdown is drawn directly on the button face.
- All numeric tunables are
constat the top of the skill-button script. - Icons are vector primitives, easy to swap for SVG/PNG later.

Building new VFX skills
New literal-3D spell/ability VFX (novas, beams, AoEs) are rendered in a pooled private SubViewport at the hero's angled look and composited into the 2D world — a real 3D effect layered onto the flat MOBA camera at low runtime cost.
