====== Open Lock (DEX; TRAINED ONLY) ====== The effort requires at least a simple tool of the appropriate sort (a pick, pry bar, blank key, wire, etc.). Attempting an Open Lock check without a set of thieves' tools carries a –2 circumstance penalty, even if a simple tool is employed. The use of masterwork thieves' tools enables the character to make the check with a +2 circumstance bonus. **Check:** Opening a lock entails 1 round of work and a successful check. (It is a full-round action.) ^ Lock ^ DC ^ | Very simple lock | 20 | | Average lock | 25 | | Good lock | 30 | | Amazing Lock | 40 |
