I went there tonight using the elf crystal tele, and I couldn't enter into the temple to get to the alter. I was wondering if I'm forgetting to take something with me to get in. In my inventory all I had was the crystal tele, and the runes, on me I had omni-Tiara, spottier cape, glory,combat braclet, boots of lightness and ROW. Is there something else I need or do I need to take something off to enter. Last time I entered was doing within the light quest, Usually when I go there it has only been for quest.

You require the crystal trinket obtained by speaking to Arianwyn (sp?). However, while this will grant you access to the Temple of Light, it is highly inadvisable to craft death runes using this method as the journey and the aggressive shadows in the area will drastically bring down your exp and profit rate, making the Ourania altar, nature runes or the abyss far better methods.

Yeah when you finish MEP2 and they give you a crystal trinket to allow you access to the re-secured temple it is for reason. You need it to get in again.

 

And as covered that way of rcing is an absolutely awful idea. Use the abyss or play GOP for the direct teletabs.
