I haven't studied either of these skills, and a look at the rules provided
for confusion, rather than clarification.
None of the skill tables that list learning times and NP cost list an NP
cost for any of the combat skills. The lore sheet for SFW, however makes
passing reference to a cost of 1 NP. Is this reference left over from the
g1 rules, or is the cost there, but not documented correctly on the other
tables?
