If Maroc tries to trade an item of insufficient value with a warlock (determined at 52913), the warlock will fire a missile/bolt at him.
Additionally, every 32 game cycles, there's a random chance a warlock will fire a missile/bolt
The 6th byte in the data sets at 27772 is an 'aggression' stat for the warlock. It affects the likelihood of the warlock firing at Maroc. The higher the number, the higher the frequency of missiles/bolts.
The animated image below shows warlock #7, the warlock with the highest % chance of firing a bolt/missile, flinging frequent bolts at a stationary Maroc.

NEXT 4 INSTRUCTIONS DON'T SEEM TO BE USED.
It looks like a similar check to the goblin warrior at 53054, where Maroc wielding powerful magic has an effect on creature movement/actions. But these instructions are never run.

Warlock is visible on screen. Every 32 frames, a decision whether the warlock is going to fire a missile/bolt at Maroc is made.

Generate a random number and compare it with this warlock's 'aggression' stat...
|
||||
| 52987 | CALL 56070 | Generate random number (returned in A register) | ||
| 52990 | LD C,A | Store in C register | ||
| 52991 | LD A,(60333) | Byte 6 from warlock's data set at 27772 determines the likelihood of them firing a missile | ||
| 52994 | RLA | Double the value of this byte | ||
| 52995 | CP C | Compare with the (pseudo) random number generated | ||
| 52996 | JR C,53000 | If it's < the random number, don't fire a missile | ||
| 52998 | JR 53080 | If it's >= random number, set up a missile to fire (53080) | ||
| 53000 | JP 53323 | Jump to creature collision detection routine | ||
