Ho and i'm playing in all perk and add description on localization file for all level 6 i add. I could be wrong but i think mostly all skill description are wrong.

example on Salvage Operations:

perk code:

<perk name="perkSalvageOperations" parent="skillScavenging" name_key="perkSalvageOperationsName" desc_key="perkSalvageOperationsDesc" icon="ui_game_symbol_scrap">
<level_requirements level="1"><requirement name="ProgressionLevel" progression_name="attPerception" operation="GTE" value="1" desc_key="reqPerceptionLevel01"/></level_requirements>
<level_requirements level="2"><requirement name="ProgressionLevel" progression_name="attPerception" operation="GTE" value="2" desc_key="reqPerceptionLevel02"/></level_requirements>
<level_requirements level="3"><requirement name="ProgressionLevel" progression_name="attPerception" operation="GTE" value="3" desc_key="reqPerceptionLevel03"/></level_requirements>
<level_requirements level="4"><requirement name="ProgressionLevel" progression_name="attPerception" operation="GTE" value="5" desc_key="reqPerceptionLevel05"/></level_requirements>
<level_requirements level="5"><requirement name="ProgressionLevel" progression_name="attPerception" operation="GTE" value="7" desc_key="reqPerceptionLevel07"/></level_requirements>

<effect_group>
	<requirement name="HoldingItemHasTags" tags="perkSalvageOperations"/>
		<passive_effect name="BlockDamage" operation="perc_add" value=".1,.5" level="1,5"/>
		<!-- wrench (or other relevant tools) do a base_add=1 to hop on the salvage train -->
		<passive_effect name="HarvestCount" operation="perc_add" value=".2,1" level="1,5" tags="salvageHarvest"/>
</effect_group>

<effect_group>
	<effect_description level="1" desc_key="perkSalvageOperationsRank1Desc"/>
	<effect_description level="2" desc_key="perkSalvageOperationsRank2Desc"/>
	<effect_description level="3" desc_key="perkSalvageOperationsRank3Desc"/>
	<effect_description level="4" desc_key="perkSalvageOperationsRank4Desc"/>
	<effect_description level="5" desc_key="perkSalvageOperationsRank5Desc"/>
</effect_group>
</perk>

Description on localization file:

perkSalvageOperationsRank1Desc,progression,Perk,New,A wrench harvests 20% faster and gains 20% more resources.,,,,,
perkSalvageOperationsRank2Desc,progression,Perk,New,A wrench harvests 40% faster and gains 40% more resources.,,,,,
perkSalvageOperationsRank3Desc,progression,Perk,New,A wrench harvests 60% faster and gains 60% more resources.,,,,,
perkSalvageOperationsRank4Desc,progression,Perk,New,A wrench harvests 80% faster and gains 80% more resources.,,,,,
perkSalvageOperationsRank5Desc,progression,Perk,New,A wrench harvests 100% faster and gains 100% more resources.,,,,,

'a wrench harvests 20% faster' should be 10%,20%,30%,40%,50%... Am i wrong?
