When killing a monster its loot drops on random cell in a 3x3 area around it.

Expected Result

When killing a monster, its first regular drop will always drop at the exact cell the monster was on. It even drops there when the monster is inside Icewall.
After that each following drop drops in the following pattern: SE -> W -> N -> SE (it repeats, but never returns to center)
If those cells are occupied by walls (including Icewall), the item will drop in a 3x3 around that target cell instead (e.g. SE can become 2S).

How to Reproduce

Kill a monster that often drops items e.g CRYSTAL_1 (1395) or EVENT_RICECAKE (1815).
Try again with walls being near it.
Try again by blocking all target cells with Icewall.

Is it possible to add the mob_loot do not show effect when drop into #8347

Is it possible to add the mob_loot do not show effect when drop into #8347

Currently no good way to differentiate between looted items and normal drops. That's why I reduced this issue also to normal drop behavior only and applied it to all. (In reality looted items actually start north.)

Edit: Good news! Looks like I found away to fix this at the same time.

Will check if the following things could be handled it one go or if a separate issue for them would be better:

• Aegis has two item lists: Looted items and all other items (regular drops + item/skill granted drops)
• Non-looted item lists drop item/skill granted drops first and the regular drops in their order from first to eight slot, the first item drops center
• Looted items drop in the order they were looted, the first item drops north
• Looted item drops are not showing a highlight (pillar)
• Both lists proceed dropping in the same order after the first: SE -> W -> N -> SE
• Items never drop on walls, icewalls and also not on CHAR|PET-occupied cells; if occupied, they drop on a free cell in a 3x3 area around the original target cell of the drop except for the center drop of a monster which will always drop there no matter what
• If a player drops an item manually it will drop on a free cell in a 5x5 area around the player (random cell)
• When searching for a random cell in both cases (3x3 or 5x5), the item will first try to drop in a random quadrant in that area without checking cells on the same x and y-axis, only if that fails, it will check the cells on the same x and y-axis as the original target cell
• When searching for a random free cell completely fails, the item always drops at the original position, even if it is occupied

(Hint: If you surround yourself by icewalls so only the cell you are standing on does not have an icewall, then all items drop on the cell you are standing on.)
