[lang=en]In 13th Age combat there is an escalation die, which is simply an incremental global addition to hit. So starting at turn 2 all PCs get +1 to hit. Then turn 3 another +1 etc. Some abilities also key off this number. This mechanic creates a climactic momentum in combat, and helps stop combat grind. I like it!
Fail forwards is just that when PCs fail a skill check or something rather than the result being a blanket No/total fail, which tends to bring progress to a halt, the DM interprets the check fail result as a success but with complications - like you pick the lock but set off a trap or make a load noise or break your picks or something. Again, this is an idea I really like!
13th Age seems to have many cool ideas ...
