Corruption check bonus if in company with a ringwraith

[Khamul the Easterling]

Characters in a ringwraith's company receive a bonus of +2 for corruption checks.

This is a rule from MELE, does it pertain to the Balrog? I daresay yes, as there is no conflicting ruling in the MEBA booklet, and all rules applying to raingwraiths generally apply to the Balrog, too. True?

[Muad'Dib]

Playing as a Balrog, you also get this bonus to ccs.

[Konrad Klar]

A Balrog player acts as a Ringwraith player. Any card and rules text applying to a
Ringwraith also applies to The Balrog (e.g., if a card refers to a Ringwraith, it now
applies to “a Ringwraith or The Balrog”).
However, instead of using the special rules listed on page 59 of the MELE rules (or
wherever else these rules may appear), a Balrog player uses the following special
rules:
• Any ring in The Balrog’s company at the beginning of the end-of-turn phase is
automatically tested. Any ring test in The Balrog’s company has a modification
of -2.
• The Balrog may carry items (including rings) but may not use them (i.e., an item
has no effect on The Balrog’s company or on his attributes and abilities).
• The Balrog never makes corruption checks and corruption cards may not be
played on The Balrog.
• Normally, The Balrog may not use starter and region movement (as stated on his
card). However, the play of certain resources can expand his movement capabilities.
• The Balrog’s company is always overt.

Underline mine.

So there is no need to translate a rules that refer to Ringwraith to rules that refer to Balrog.
Only card's effect need to be so translated.

However, the corruption check modification rule is not mentioned on p. 59. It is mentioned under the rules for corruption checks, so it does indeed apply to the Balrog, as well.

[Konrad Klar]

Yes.
I should underline "and rules text applying" for myself...
