Weaver of Fates

The psyker traces the skeins of the future to see the fates
of battle. Forewarned of imminent danger, warriors
dodge bullets and sword blows with seemingly supernatural reflexes.
Weaver of Fates has a warp charge value of 6. If manifested, select a THOUSAND SONS unit
within 18" of the psyker. Until the start of your
next Psychic phase, the invulnerable save of that
unit is improved by 1 (to a maximum of 3+).
Models that do not have an invulnerable save
instead gain a 5+ invulnerable
