Spiders can shoot webs (Scytodes thoracica for example) imbued in venom (about this scientist are not sure). Furthermore in a wordl were spiders can tekeport where is the problem if they also shoot venonous webs from distance? O.o.
The problem is that SPECIFICALLY BY THE RULES DECIDED FOR THIS WORLD Phase spiders are supposed to be among the species of spiders that DO NOT use range attacks and are defined by their phasing ability and their melee attacks.
There are OTHER species of giant spiders that are supposed to have ranged attacks, but Larian doesn't seem to care about the minor nuance.
It's not even just flavor, since changing the abilities of an iconic creature of the D&D bestiary changes entirely the shape of any combat involving them.
Anyway, this is OT and it was already discussed at length in other more pertinent threads more focused on the bestiary, encounter design, etc.
