+# Stanek
+
+Allison is a bit crazy.
+But her special [Augmentation](../basic/augmentations.md) is very useful despite its ~~bugs~~ features.
+The Gift consists of a grid of squares in which tetris-like pieces called fragments can be placed.
+Each fragment boost a different player multiplier.
+However, the fragments are not very powerful by themselves.
+
+To increase the power of a fragment, the `ns.stanek.charge()` function needs to be called.
+More threads means more power.
+
+There are also special fragments called booster fragments which increase the power of the fragment it touches.
