Enchanted Realms Rulebook
Standing Up
When one is in the prone position, a reaction can be used to stand rather than waiting until the start of his or her turn. Much of this has already been discussed in the Ground Rules subsection, but this description should clarify a few additional points.
Movement is free but certain changes in position require either a full action or the use of a reaction with a movement cost. Standing up from being prone is one of those requirements. Thus, to stand one must either sacrifice an action or a reaction (player’s choice) to accomplish this. Most often, the reaction will be selected, as it can be used at the start of the round or just after being knocked down.
As explained, using the reaction will still incur penalties to movement. That penalty is half of the standard movement for the creature’s species: 20 feet for human, 15 feet for dwarf, etc. It is not half the character’s standard movement, as it might be enhanced by magic or skills; thus, the species standard is used instead. However, this may be why the action to stand is used rather than a reaction, as selecting the action will not incur the movement penalty and it is effective instantly.
The timing for standing up is important as well. When prone and standing up with a reaction, there is a d4 delay on the initiative counter for when the new position changes. In the interim, the prone restriction is still applied. Also, if the delay extends beyond end of the round, then use an “around the corner” technique to determine the appropriate second-counter in the following round. Thus, if the reaction is used in second-counter:2 and the delay is 4 seconds, then standing will be effective in 10 of the subsequent round. To reiterate, if using an action instead of a reaction, standing up happens immediately.
Finally, the reference to standing up here applies only from a prone position. As a rule, standing from a chair is not considered as having been prone. Of course, the GM might rule differently if perhaps someone had been shoved into the seat.
