I'm actually curious how true this is, because it seems like this would come with a lot of caveats due to the diminishing returns that occur when a talent is leveled up.jenx wrote: 7. Talent concentration - except for a few rare cases, most characters benefit from maxxing a few talents rather than spreading. So a great way to learn tome is to pick a class, and one or at most two trees. And dump everything into them. your stat points into its stat, every class point, everything you can. you will probably die, but you will also start to understand how talents really work. the trick to tome is that talents can be very very different at high levels. some become less and less useful (e.g. ones that boos defence imo) and others that seem mediocre can become hugely powerful.
There are some particular abilities that get significantly more powerful due to either secondary affects (Distortion Bolt allowing distortion effects to ignore allies at level 5) or due to their particular method of scaling (if you're getting Bone Shield, sink all five points into it) but those seem to be the minority. As a counter-example, a corruptor will do more overall damage with 3 Soul Rot, 3 Drain, and 3 Blood Grasp than, say, 5 Soul Rot, 4 Drain; or 5 Soul Rot, 3 Drain, and 1 Blood Grasp, since each point that you put into a talent yields less overall value than the point that came before it.
It just seems like saying "Only stick to two trees, concentrate" is poor advice in most cases.
