Summon Net-Spider (Rank 5) Edit
The Garou can summon a Net-Spider, a Weaver spirit that gives its summoner near-absolute control over any computer system. The Spider can disrupt, erase or destroy whatever system it is sent into (the exact effects are left to the Storyteller, but are typically destructive). An avatar of Cockroach teaches this Gift.
The player spends one Gnosis point and rolls Charisma + Computer (difficulty 8). If successful, the Net-Spider appears and heeds the Garou's commands. This Gift allows the Garou to halve all computer-related difficulties along with the aforementioned destructive capacity of the spirit.
