Pathfinder is very different mechanically to dnd

Is it though?

Depends on which edition of DnD, frankly. Pathfinder 1e and 2e are quite mechanically different, as many DnD editions are to each other.

Pathfinder is closer to D&D than most other TTRPGs (not counting direct D&D derivatives)

blindness/deafness is a 1e spell which is permanent no matter what

Breaking Hasbro IP is chaotic good though

I'd rather not give them the recognition, and Pathfinder ditched alignment anyway.

It is actually a good strategy to dilute the term Dungeon Master into a general phrase, because that means Hasbro can't enforce their copyright. For instance, Aspirin is a brand name, but it's such a generic term that anyone in the US can call their product Aspirin without risk.

True, but anyone who thinks it's a drag and drop replacement is in for a headache

We'll have to agree to disagree! I prefer using the game's defined term, or Game Master for general usage.

I need to read up on Pathfinder 2e.

I know the "joke" was that 1e was basically D&D 3.75... which was a bit too powergamey for my tastes, so I never even looked at 2e...

D&D 3.5:

Blindness/Deafness Necromancy Level: Brd 2, Clr 3, Sor/Wiz 2 Components: V Casting Time: 1 standard action Range: Medium (100 ft. + 10 ft./level) Target: One living creature Duration: Permanent (D) Saving Throw: Fortitude negates Spell Resistance: Yes

You pretty much destroy their eyes or ears. There's a spell that undoes the damage

So can wizards quietly cast spells in a stealthy manner? Want to know if I ever get isekai'd into a pathfinder world.

AFAIK The (D) behind „permanent“ means „dismissable“ so the caster can end it any time they want.

Conceal Spell

Through sheer mental effort, you can simplify the incantations and gestures needed to spellcast, leaving them barely noticeable. If the next action you use is to Cast a Spell, the spell gains the subtle trait, hiding the shining runes, sparks of magic, and other manifestations that would usually give away your spellcasting. The trait hides only the spell’s spellcasting actions and manifestations, not its effects, so an observer might still see a ray streak out from you or see you vanish into thin air.

Silent Spell (Metamagic)

Benefit: A silent spell can be cast with no verbal components. Spells without verbal components are not affected. A silent spell uses up a spell slot one level higher than the spell's actual level.

Doesn't work for Bard spells, although they have a way to disguise theirs:

Melodious Spell

You subtly weave your spellcasting into a performance. If the next action you use is to Cast a Spell, the spell gains the subtle trait, hiding the shining runes, sparks of magic, and other manifestations that would usually give away your spellcasting. The trait hides only the spell’s spellcasting actions and manifestations, not its effects, so an observer might still see a ray streak out from you or see you vanish into thin air.
