Custom text, drop/spoil, is it legal?

[Zrips]

So just basic question about option to change default chat combat log text to something more... Useful... And to add drop/spoil to monsters. Is things like that counts as illegal and not permitted or do we actually could do this? Its not game changing or providing advantage, its simply simplifies life when i can actually see useful information in combat log and separate messages one from another instead of looking at 100+brown lines and trying to figure out which is which...

You know there is a 'mark keywords' feature in chat. You can use this to detect anything including 'spoil condition activated'.

Modifying the game's files is, however, prohibited and you will end up flagged (if your game isn't going to be simply blocked from starting) by XIGNCODE.
