{1}{G}, Sacrifice Renowned Weaver: Create a 1/3 green Spider enchantment creature token with reach. (It can block creatures with flying.)
If Renowned Weaver is attacking or blocking, and you activate its ability before combat damage is assigned and dealt, it won't deal combat damage. If it was blocking a creature, that creature will remain blocked. If you don't activate the ability before the combat damage step, it must survive combat for its ability to be activated later.
