Registration permissions
| Registration | Handler | Required status (local DB, Oct 6) | Implementation |
|---|---|---|---|
/useability |
34 | 0 | Implemented |
Cast a spellbook ability.
Implementation: Implemented.
Syntax
/useability <spell_id> [tier]
Arguments
Position is zero-based in sep, after a registered database subcommand has been removed. Internal action tokens remain at position 0. Angle brackets are required; square brackets are optional. Alternative forms may change field meanings.
| Position | Argument | Accepted value / type | Meaning |
|---|---|---|---|
| 0 | spell_id |
unsigned integer | Spell identifier. |
| 1 | tier |
unsigned integer | Optional tier; normal spellbook tier handling applies. |
Behavior and restrictions
- Requires a living caster and the normal spell availability/casting checks.
Current argument/client/target checks (exact source excerpts; branch-dependent):
if (sep && sep->GetUInt(0, spell_id_val)) {
if (sep->GetUInt(1, spell_tier_val))
Permissions
Local database snapshot, October 6, 2026: /useability requires status 0 (handler 34). Other worlds may configure different values.
The dispatcher checks the resolved registration status before invoking the handler. In-handler guild, group, ownership, client-version and target checks still apply.
Examples
The syntax forms above are the source-based invocation examples. Replace identifiers with values valid for your world; client callback fields are supplied by the game client.
