Effectiveness
From MHWiki
Effectiveness refers to the bonus (or penalty) when using a Trap against Mice of different Power Types. It is believed to be a modifier applied on the Power or Luck values of a Trap, or possibly both.
Players should avoid hunting at a location where their current traps will be less effective against most of the mice there, such as the Mousoleum without a Shadow/Arcane trap, or the Furoma region without a Tactical trap.
Effectiveness Levels
A Trap can have 1 of 3 possible effectiveness levels against a mouse:
- Very Effective
- A very effective message implies that there was a bonus to the trap power/luck in catching the mouse. No message is shown if the catch result was a miss.
- Normal Effectiveness
- No additional message is shown for a normal catch. This implies that no modifier has been applied to the current trap power/luck in catching the mouse, and is the most commonly encountered effectiveness level. No message is shown if the catch result was a miss.
- Less Effective
- A less effective message will appear when there is a penalty to the trap power/luck in attracting a mouse and the catch result was a miss. This usually indicates that the wrong trap type is being used for the current location. No message is shown if it was a successful catch.
- Note that trap effectiveness has no bearing on the Attraction Rate of a trap and the type of mice attracted, which is dependent on the baited cheese.
