Maroc has cast some other spell:
55320	LD A,(60359)	Check the type of spell cast
55323	CP 2	Spell type 2 = spell that generates a controllable graphic, e.g. SERVANT, MISSILE, OPEN
55325	JP NZ,55553	If not one of these spell types, skip out of this routine for other checks
Spell has been cast that involves a controllable cursor: Bit 7 of the spell info byte at 60362, if set, tells us this is a missile/bolt aiming cursor If not set, it's a spell whose cursor position will need checking for room events/collisions (SERVANT, OPEN, REVEAL etc.)
55328	LD A,(60362)	Get byte indicating spell cursor type
55331	CP 0	If not active, can skip to next routine
55333	JP Z,55553	If not active, can skip to next routine
55336	LD C,A	Otherwise, temp store this value in the C register
55337	AND 128	Bit 7 of this byte is set for bolt spells (MISSILE, FIREBALL etc.)
55339	CP 0
55341	JP Z,55474	If NOT set, it's another sort of aiming cursor, so can jump out here and deal with this spell's potential event/collision actions
55344	JP 55553	If set, it's a bolt/missile type spell, fine to jump out of this routine
