Advantage/Disadvantage
Having advantage on a roll means you roll the die twice and use the highest outcome. Having disadvantage means you roll twice and take the lowest outcome.

Saving throw (save)
A check made to resist certain effects, usually magical or poison-based. See 2.1_Combat.

Sneaky step
If you take no movement actions in a certain round, you can move one square for free. This is called a sneaky step.

Dazed
A dazed creature takes disadvantage on attacks and checks, except con checks and int saves, and grants advantage on attacks made against them.

Grappled
A grappled creature is being physically restrained (or is occupied restraining someone). They take disadvantage on attacks and checks requiring movement, and provide advantage to attacks made against them. Note that since these penalties usually apply to both participants, they take no penalty on attacks against each other. They can't move without using the drag action.

Prone
A prone creature is laying on the ground. They take disadvantage on attacks and checks requiring movement, their speed is halved, and they can't take sneaky steps. Melee attacks against them have advantage. Getting up can be done as part of a move action, costing half your potential movement (e.g. 3 squares if your speed is 6).

Stunned
A stunned creature can take no actions, and grants advantage on attacks made against them.

Unconscious
An unconscious creature automatically falls prone and can't take actions. Its defence becomes 1.
