TWIRP Weekly Winners and Losers (2008/01/28) TWIRP Combat and Monster Drop Value Indexes Report and Analysis (2008/01/28)

This section of the report highlights the weekly results for the skill-based indexes. There are two different types of indexes tracked here: composite indexes broken down by level (which include all skills), and indexes by skill type (which include all levels). For more details on these indexes, please see TWIRP Skill Indexes; if you are not familiar with TWIRP as a whole, please refer to the TWIRP Quick Guide before proceeding.

Skill Composite Yield (Low-Level) [TWIRP-S(l)]: 99.2 +1.0% p

Lots of winners and losers this week, with few skills remaining near unchanged. As mentioned earlier in the report, the main winners are the skills that produce much demanding items for combat: potions and food, mainly. This group is led by Farming and Herblore, skills that I earlier predicted would benefit from recent seed price drops and demand for potions. Fishing rebounded nicely this week, which, again, I had predicted last week. J

The losers were... pretty much everything else. Slayer is being hit hard by more people trying to train it as they hunt for charms for Summoning; huge quantities of unique Slayer drops are flooding into the market, and I expect this to continue for a while unless drop rates are changed. Construction was hit by adjustments in previously price-locked item prices on the GE, while Fletching was similarly hurt by formerly bogus bow prices being unlocked. Runecrafting continues to bounce around as pure ess prices do.
