As a pre-painted miniatures collector and a GM, I relish the opportunities to raid my miniature stock and throw down a hand full of orcs, skeletons or goblins for the players to encounter. As a GM, keeping track of HP's of each creature can be a little confusing, especially of the creatures which have a fair amount of hit points, and move around quite a bit each turn.
Over the last year I have been using the Alea Tools base markers to keep track of my bad guys. Using their adhesive number strips, the ability to track each bad guy by number is made very easy.
The intent of these base markers though, was that they expected people to buy their metal stickers to be affixed to the bases of your miniatures. (Clearly not an option given the amount of minis in my collection). While its nice to have the bases themselves to be magnetic for stacking/storage purposes, I felt like I was missing out on one of the key features of the bases. Since I did not apply magnetic backers to my minis, I often found I was having to try to slide the minis around to keep them from falling off the base. It was a bit clumsy at times, but it worked good.
One day I decided to place a small ball of Super Sculpey clay on the marker and place a mini on it. It held really well. Although Sculpey is not tacky to the touch, it really bonded the mini well to the base marker. When it came time to remove it, it remove very easily and left no residue. I have continued to use the same pieces of Sculpey over and over again and I do not find it to be loosing its tackiness.
I thought this might be worth mentioning to others who would like a nice clean way of attaching and detaching their minis to numbered bases.
