There is a bug with perks related to STRIKE DAMAGE and LIGHTNING DAMAGE.
The PERK termed Lightning Protection, only applies to NECKLACE slot item =
The PERK termed Strike Protection, only applies to NECKLACE slot item =
There are both Lightning and Strike Damage in the game, there is no actual perk that reduces damage from STRIKE damage though. It seems, the effect for Strike Damage is wrong, it should be protecting from STRIKE damage, not LIGHTNING damage.
ALSO… both Lightning/Strike SHIELD WARD are the same, there is no actual protection from STRIKE damage for shields… AND, half of the shields will LIST shields with the perks in Trading Post searches, yet when hovering over the shields to check, they DO NOT have either of the actual perks.
CONCLUSION: Very Buggy.
Change Strike Protection to; Protects from Strike Damage (used on Amulets)
Change Strike Shield Ward to; Protects from Strike Damage AND ensure Perk Tag is correct for all shields and Trading Post searches.
Keep Lightning Protection as; Protects from Lightning Damage (used on Amulets)
Keep Lightning Shield Ward as; Protects from Lightning Damage AND ensure Perk Tag is correct for all shields and Trading Post searches.
