How many weapon mods can you put on a weapon?

Ive got a scythe and i perf salvaged the crapp mods off it. Then I stuck a 15^50 on it. Was also thinking of getting a +30hp mod for it..would it be worth it?

Is there a max mod limit ? (I know there is but how many mods can you put on it untill it overwrites the last)

Pretty sure you can have:
1 on the scythe grip
1 on the scythe snathe
1 inscription

So... 3 total for each weapon, ex. bow = string and handle etc.

One prefix (like sundering), one suffix (like fortitude), one inscription (like strength of honor).

I see. Thanks guys

Weapon items like Wands, Focus items and Shields can allow 2 - one inscription and one mod.

Mods are overwritten if you try to place one on when one of that type already exist on it. e.g. a sword with an Icy hilt, if you try to place a Furious hilt on it then you can end up losing the Icy hilt if you confirm to do so.

Read the box carefully when you're upgrading, you might be covering over your previous mod.

The mods come in parts of the weapons, which are conveniently differentiated by shapes.

Why perf salvage crap mods off? If you put an upgrade on then it replaces the current one of it's kind...i know this because i tried to salvage bowstrings off stormbows before and..oop snap. Only to find out they could have just been harmlessly over-written -.-

Yeah.. I wasnt thinking, Oh well.. no harm done

These two Wiki pages might help:

You don't have to remove the crap mods (and/or inscription) to add new ones! When you add a new mod it "overwrites" the old one!

Already been said o_o
