Based on technology developed by N-trig (a separate company at the time, though subsequently acquired by Microsoft), the Surface Pro 3 version lacks the eraser tip present in the previous generation; erasing is done by drawing over the ink strokes while holding down one of two physical buttons on the side, above the button used for right-clicking. A third button, located in place of the eraser tip, sends a Bluetooth signal to a paired Surface PC which instantly opens OneNote, even when the device is locked (although advanced editing functions are disabled in this case). Unlike the Wacom-powered Surface Pen, it requires two batteries: one AAAA battery for stylus operation, and two size 319 coin cell batteries for the top button. The pen is included with all Surface Pro 3s but is also compatible with and available as an optional accessory for the Surface 3. It is also compatible with all subsequent Surface PCs, which uses the same basic technology. Surface Pro 3 Pen is able to detect 256 levels of pressure on its tip.

Normally a pawn moves by advancing a single square, but the first time a pawn moves, it has the option of advancing two squares. Pawns may not use the initial two-square advance to jump over an occupied square, or to capture. Any piece immediately in front of a pawn, friend or foe, blocks its advance. In the diagram, the pawn on c4 can move to c5, while the pawn on e2 can move to either e3 or e4.

Results depend on how each poison is processed by the body, ie, on how the toxic compound is metabolized or passed out of the body. In some cases, it is possible to build up tolerance against specific non-biological poisons. For some poisons, this involves conditioning the liver to produce more of the particular enzymes that deal with these poisons (for example alcohol). Another mechanism involves conditioning the target tissues of the poisons. These methods do not work for all non-biological poisons. Exposure to certain toxic substances, such as hydrofluoric acid and heavy metals, is either lethal or has little to no effect, and thus cannot be used in this way at all. Arsenic is a notable exception with some people actually having a genetic adaptation granting them higher resistance which can be replicated with mithridatism. In addition, simple toxins that work through chemical processes that bypass the immune system cannot be dealt with (good example would be the variants of cyanide).
