API IsPlayerSpell

Returns whether the player has learned a particular spell. isKnown = IsPlayerSpell(spellID)

• spellID: - Spell ID of the spell to query, e.g. 1953 for Blink.

• isKnown: - true if the player can cast this spell (or a different spell that overrides this spell), false otherwise.

• Spells can be permanently or temporarily overridden by other spells as a result of procs, talents, or other spell mechanics, e.g.
• Moonfire is overriden by Sunfire while in Solar Eclipse
• Trap Launcher replaces trap spells by ranged variants
• Nether Tempest replaces a permanent base spell Mage Bomb
• Chakra replaces Holy Word: Chastise with different spells
• Querying the base (replaced) spell will also return true if any of its overrides are currently active.
• Querying an overriding spell may or may not return true even if that spell is currently known, depending on the particular spell.
