I don't remember offhand but I feel like some of my characters have had full LOS? Maybe it was one tile short. Here's an example character:
http://crawl.akrasiac.org/rawdata/Tason ... 042649.txtFor those who don't want to look: Vinestalker with 47 int (Chei + equipment), 18.4 spellcasting, 18.6 translocations (Cblink at 1% fail, lesser beckoning 0% fail). 8 #'s of spellpower (between 100-149), but thankfully the game protects me from knowing exactly how much spellpower I had
That's obviously overkill for just getting lesser beckoning range, but if you're going to learn Cblink anyways, you get some handy beckoning range "for free".
