Feat to make haste not break invisibility

[Vlaid]

Either still spell, silent spell or improved initiative (or a combination of Still/Silent and Improved Initiative) might offer the additional bonus that when you haste while under the effects of invisibility it does not break. Would only apply to haste you cast yourself (ie, a fighter or multiclass should not be able to take it for the purposes of using potions).

Primarily intended to be an option for wizards (with their extra feats) as it would be a bit cost prohibitive to other casters.

Sorcerers/Bards/Clerics only Silent Spell, Wizards Silent Spell + Improved Initiative (Since they have more feats to burn, spend that currency if you want to easy gank oven).

I dont know, I think this would make it too easy for wizards to suddenly appear with CC + blasting and completely obliterate people. It seems (to me, at least) already easy enough as things stand... So allowing others a 6 second reaction time feels quite alright!

Also, I do think the feats proposed don't really make that much sense (shouldn't it be something related to ilusion/trasmutation?). After all, this wouldn't only apply for ganking situations, but also for travelling and the like.

That said, it'd be good if Silent spell allowed invisible casters to not cause the "you hear someone chanting..." message. That would aid in ganking without being overpowered.

Invisibility is already the strongest spell in the game, it needs no further buffs

The point is to create options that are more feat tax heavy as additional options primarily for wizards.

That was always the case for a long time and it was relatively fine.  The reason it wouldn't be done off a GSF is those already have a large built in use and would just make most casters get it by default, so there would be no point. If you have to go out of your way for an otherwise not very good feat it has a purpose.
