We have a cool large weapon. Also we have mythic tier and some fun.
Druid has a guardian's ability to PARTLY transform his body, and wants to wild shape in, for example, giant elk or something large with human torso.
The question is: what size will be a large weapon in his hands?
If we are talking about enlarge person - it affects weapons, but what about this situation?
And also: how could I get this weapon be used in one hand with other effects? Because with enlarge or righteous might it becomes huge :(
Thanks!
But what about T-REX with human torso? My armour will crush me, I suppose? :)
You could just go goliath druid. They trade away a lot of wildshape options (elementals, plants) so they can turn into giants instead.
With that, you can just pick up your large weapon whenever you want.
Of course, it is hardly a reason not to use a medium weapon. Since they turn into humanoids, their equipment changes size with them.
This is a generally tricky topic because of the mythic ability and the way the polymorph rules are written. The main clause that deals with items and wild shape is this one:
When you cast a polymorph spell that changes you into a creature of the animal, dragon, elemental, magical beast, plant, or vermin type, all of your gear melds into your body.
So far so good, covers all normal use cases of wild shape. The problem comes in when you try to add in partial transformations via the mythic path ability. How do you determine the creature type for a partial transformation to determine whether gear melds or stays usable?
Regardless, any gear that doesn't meld will change size with you with any polymorph effect:
If your new form does not cause your equipment to meld into your form, the equipment resizes to match your new size.
Enlarge Person has the clause about equipment changing size because Enlarge Person is NOT a polymorph effect.
Just talking about large weapons and effects, that enlarge you.
"Match the size" - intresting... What about large greatsword is already matching my size now?
And yes, goliath druid enlarges his equipment... or not?
For example: I want to become giant creature - tentacles of giant octopus in place of legs and torso of giant human. So I can partly keep my armour and keep my head to cast spells and arms to wield a weapon and shield.
The next question will be: can I wield a LARGE magic one-handed weapon with one hand, being large?
About armour - it's not a problem, just make it "wild", and it will fit in every form.
Goliath druid giant shape is based on alter self, and alter self is a polymorph effect, so yes, when using that your gear would change size with you.
As for the octopus thing, again, the mythic ability is pretty vague. It's going to have to be a judgement call for your DM. The way I would rule it, for example, would be that your armor would meld (you can't keep just part of your armor unless you're using optional piecemeal armor rules or something), you'd keep the weapon and shield, and you'd only get one tentacle per leg if you're not changing all your limbs. There's really not a lot of guidance in the ability, though, so if you ask 10 different DMs you'll probably get 10 different answers.
And when using mythic ability?

Strictly speaking it says match, not scale. If you were using an oversized weapon, it would match your size not scale up one size.

As mentioned before, ask the GM running the game how they will adjudicate it.
