Set Targets number and targets ID list for most of reaction abilities (except counter abilities and auto potion - not supported here and flag 0x08 enabled)
------------------------------------------------------------------------------
Parameters: r5 = Attacker misc action data (misc 0x18c) r4 = Attacker ID
r6 = Main ability inner stack pointer 1 (r29 0x28)
r7 = Main ability inner stack pointer 2 (r29 0x10)
Returns : r2 = 0x01 if reaction is reflect distribute or damage split (failed or not)
r2 = 0x01 if other reaction with flag 0x04 enabled
r2 = 0x00 if other reaction with flag 0x08 enabled
Store : If Reflect : Target coordinates in misc attacker data 0x1c 0x1d 0x1e
List of targets ID at previous routine r29 0x10
Number of units hitted at previous routine r29 0x28
