My Fighter has taken a level in Kensai recently, but I've yet to enhance his signature weapon (which is just a perfect greatsword for now) because I want to be sure that I can make it glow like a magical weapon.
The DM of the game I'm playing is pretty strict on rules and generally only accepts RAW or, in cases where multiple manuals need to be used, takes the most literal intepretation possible.
Therefore I want to be sure I'm understanding the rules correctly.
The Complete Warrior manual, in the section about Kensai enhancing their weapon says:
The process for imbuing a signature weapon with power is a simple one. The character must find a quiet, safe spot to meditate (and pray, for those kensai who serve deities) for 24 hours. At the end of this meditation, the kensai sacrifices a number of experience points, essentially shifting some of his life force into his signature weapon. The signature weapon then becomes a magic weapon (if it wasn't already) and gains an enhancement bonus and/or special abilities.
(emphasis mine)
The Dungeon Master guide on the subject of creating magical weapons states the following:
[..] At the time of creation, the creator must decide if the weapon glows or not as a side-effect of the magic imbued within it. This decision does not affect the price or the creation time, but once the item is finished, the decision is binding.
Considering this, is it correct to say that RAW a Kensai can decide to make his signature weapon glow when by imbuing it with power he turns it into a magical weapon?
