conveys whatever meaning you intended when you wrote the text

So this mean that regardless of what language it's written in, it would be "understood" by the intended reader?

I'd say so.

Not just for forgeries! 

• You can stick a note to someone's back that only a few people can see.
• You can use it around religious types -- when they realize they're the only one who can see it, maybe it's a message from their god!
• You can make graffiti on a wall that looks like 'up with the king' to the cops, and 'down with the king' to the peasants. All sorts of mischief.

 It takes at least a minute to cast so they seem pretty likely to notice you casting it.

Also, given they they could have said "any surface" but went with ""suitable writing material", I'd say that the spell wouldn't work on someone's back.

Honestly, for 10 gold I don't think its really worth it to use it for those other uses you mentioned. Forgery (including making changes to existing documents) is by far the best use of the spell.

With an emerald pen (uncommon), we can now cast this at will without the 10gp cost :D

trick people into signing away their souls with a contract that they can only read a false illusory version of!!!
MWAHAHAHAHAH

Not to be a "hum actually" person, but magical contract cannot be agreed to by mistake. The deal making only occurs if the person is actively and knowingly agreing to the terms of the contract. You cannot sell away your soul unknowingly.

 ► First of all, I don't believe there's anything in any of the source books that suggest such a rule. It'd be up to the Dungeon Master to decide if that sort of rule takes place in their world (and in the games I run, it's fair game).
► Secondly, there's no reason the contract itself has to be magical. Any unscrupulous devil, fey, or celestial can simply make the claim that they are in their rights to take someone's soul with their own power, citing the contract as the authority which grants them the right.

It's like fine print, that anyone with truesight can read. I you don't look closely enough (or can't, hehehe), it's your own fault as far as evil NPC/PC is concerned.

 By those rules, no one would ever sign anything ever, because it could be one page of a multi-page contract that sells their soul.  Or have microscopic or invisible writing to the same effect.  Or the fiend could erase everything except the signature, and write in a soul contract on the page.  Everyone's soul would already be owned by some extra-planar entity.  Which is fine if you're playing a dark humor campaign, but wouldn't work in other games.  That's why understanding & intent are part of contract law in the real world.

use this to trick devils when writing up contracts

Ignoring the debate above over whether such a contract would actually be binding, most devils making a contract of that sort of significance have Truesight.

"Should the spell be dispelled, the original script and the illusion both disappear." Feels like there should be something similar out there that DOESN'T cause the original script to disappear too. The idea of a note being passed along that says one thing, but then you check it later and it's something else... that could have its uses for DMs and players alike. Or one that COULD be dispelled as a way around it. But with this being a 1st level spell, there isn't much wiggle room for something technically "weaker" (but better for plot devices IMO lol)

If u want, do that! You’re the Dungeon Master
