Monster spells can not be used in melee

[GuardianDll]

Describe the bug

The game dont allow to use spells for monsters, if the enemy on 1 tile range, and use default melee instead (which is not okay sometimes, especially if you try to make AoE melee attack)
for example:

Steps to reproduce

0. Give your character Debug invincibility
1. Spawn boomer glutton
2. approach to him on 1 tile range
3. spam .
   You can see it doesnt vomit sludge and spews bile anymore, instead it only attack you in melee

Expected behavior

Allow to use spells in melee combat, same as another special_attacks
or
Make a field in special_attacks, that allow to use the spell in melee combat

If you're invisible you're not a valid target for special attacks - random-walking or scent/sound-tracking monsters bumping into you trigger a normal melee attack.

[GuardianDll]

it doesnt work with another monster either

[GuardianDll]

oh, mistake, i write "debug invincibility"

[Venera3]

Okay, the problem seems to be that they have a 1-turn cooldown on bites and a 28-turn one on the spell. Bumping the bite cooldown to 2 lets them get a spell off when in melee range.

[GuardianDll]

if it were that easy i didn't open the issue here
"cooldown": 28 -> "cooldown": 2,

(i test it with another creature, that had 0 cooldown, this is just the closest example that has spell attacks)

[Venera3]

You want their bite to be on cooldown. If you set their bit to 2 turns they can fire the spell (unsurprisingly, I tested it before commenting...).

[GuardianDll]

hmmm
just delete all another attacks, and it began to use it.
thats odd, because in #55509 mon_shambling_mound in almost same conditions use it only once per 5-10 seconds, and totally ignore it if there is no "PACIFIST" flag, and i dont understand why

[Maleclypse]

This looks good to close, if I'm reading this correctly if you have one special attack that can be used every turn then the monster will use it every turn and never use their other attacks?
