You can make an Athletics check to go at your normal speed. It’s harder to wheelchair uphill than it is to walk uphill, and that can slow you down. It’s D&D, after all, and this is an acceptable break from reality.) (In real life, grass – even just a lawn – impedes wheelchair movement. This extra cost can be avoided with a DC 15 Acrobatics or Athletics check – you power through what impedes your path, or skip over it – to only suffer the standard penalty, and go half of your normal speed through difficult terrain. Therefore, you would move at a third of your normal speed. It costs one extra square of movement, in addition to the normal movement penalty, to travel each square of difficult terrain. “Difficult terrain” is even more difficult to cross when you use a wheelchair. On a smooth and level surface, it doesn’t matter whether you travel by walking or by wheelchair, both would be just as fast. To make things easier, your base speed in a wheelchair is the same as the base speed for a member of your race and class.
