Drachnids in FV and Giants in FM - all see invis - Resolved

[Sparkin]

I'm pretty sure that only a small minority of the drachnids in FV should see invis instead of all as they are currently implemented.

Same thing for all giants in FM. Not sure if any of them are supposed to see invis, but definitely doesn't seem right that they all do.

Fixed, pending update.

Reworked this some.

-FV spiders, pilgrims, and drolvargs will randomly see invis.
-Dreadlands spiders, drolvargs, giants will randomly see invis.
-FM giants will randomly see invis.
