+1 at least i agree with the basic idea of boosting chance to find the one thing you hunt most, if that's what you mean. If i misunderstand this idea, sorry.
What about "Scout-Boy" though. Doesn't that help a bit?
No im not talking about chances! its about making the encounter larger but only by the specific enemy you looking for...
Scout-Boy gave me this idea in the first place.. its a realy good feature why not bring it to the next lvl? Scout-Boy has the same idea as Nitue encounter finder with the difrence you not searching for specific enemys instead it shows you what you can finde in that squere. Anyway lets keep talking about any idea is good..
Increasing the chance is also an option if my idea is too complicated at all.
