Combining of 2 special abilities for a unit costs extra 25% in SMACX. There is an incosistency, a bug: the "free cost" abilities (like Deep Radar or Trance and ECM) are sometimes free even in combination, sometimes not. How should it be solved?
Combining 2 abilities should always raise the price of the unit.
3 (33.3%)
A "cost free" ability should never raise the price, even when combined with another ability.
God, from the mount of Sinai, whose gray top
Shall tremble, he descending, will himself,
In thunder, lightning, and loud trumpets' sound,
Ordain them laws.
~ John Milton, Paradise Lost, Datalinks
