You can workout with Logan if you discouraged him for attacking the bandit camp which increases it.
I normally have to use 3-4 lures in 1 battle to catch a Lizard.
Each turns on the lure equals 1% chance of taming him/her when you beat him/her, each use of the lure adds 25 to the counter and it goes down after each turn you and the lizard does, if you are above 100 when you beat him/her, you catch him/her every time, but below 100 or higher, there is a chance to catch him/her each time.
