Thanks for the update Greg. I didn't want to give anyone false hope given the fact that spell effects were not specifically called out as an option.
Regarding the Steeder mount and the mounted combat rules, it works fine. The text of the certificate specifically states that it can be used by a mount by any medium or smaller character. Specific (the steeder cert) trumps general (mounts must be at least one size larger).
I got that. Not trying to be argumentative, but the weight rules don't work out for most cases. Do we just ignore the weight restrictions?
A dragonborne weighs 300#...
Lets take the intent of having a Duergar riding the cert'd steeder.
It's carry capacity is 225# (15 str x 15).
A typical Dwarf weights 150#. Add an Exotic saddle for another 40#. Thats 190# and you have only 25# for everything else (weapons, armor, stuff).
Even a rogue with just leather, a bow and standard items exceed the carry cap. Let alone trying something in bigger armor.
Most mounts work because they are Large and double their carry capacity.
If this was a mount designed for medium characters, it should be large.
No biggie, it is what it is...just not well thought out. But I appreciate the effort.
