From the Guide, here’s one more foundational stone of Malkioni magic – Tapping:
Tapping is the sorcerous conversion of a local manifestation of a Rune into raw magical energy, which then can be used by the sorcery to power other spells. For example, a sorcerer learned in the Stasis Rune, might tap the Stasis out of a rock, reducing it to dust, or another might tap the Life out of a tree, killing the orchard to get magical power.
Most Malkioni, except the Brithini, Vadeli, and Waertagi, consider tapping to be immoral and evil. However, the principle is inherent in Malkioni philosophy and is easily derived from the logical techniques the Malkioni use to summon, command, or combine runes.
