World Tree swords

A merchant-only line with twice a delivered sword's base value. It changes form every 2 grades up to Yggdrasil, the World Tree at +20.

Swords of this line never come in the daily delivery. Every ghost merchant visit (days 3, 6, 9 and every third day after) has one special-sword slot, and it rolls World Tree, Fishblade or Funerary with equal odds. It arrives at +0 before day 9, at +2 on days 9 to 14 and at +4 from day 15. On the first visit it costs 2,960. Buying it needs empty hands, since the merchant puts it straight into them.

A Great multiplies value by 2.5 rather than the 2.25 that two levels would give, so a blade that climbed on Greats is worth more than this table.
