| Synthesize is the process used in game to upgrade resources, jewels and Upgrade Tomes to their next level. It is done at the Forge. This is the only way to get Jewels of level 5 and above (and in practical terms, of level 4 too, see Jewel Crafter).
These upgraded resources can later be used to

Strategy
Synthesizing may be useful to reduce the number of resources you may lose in the Prison, since the only resources you may gain or lose there are the lower tiers.
Since each level different level of jewels and upgrade tomes occupy a separate slot in the inventory, it is useful to think strategically and not upgrading them at the first chance, but wait for a convenient moment when you are ready to use the new items immediately. See inventory for details.
Once you break into the 31+ levels, it may be useful to upgrade one of your tower types and one of your magic skills more that the rest, to reach level 41+ and maybe even level 51+ before the others. This may help you to deplete the higher-quality resources in different quantities, allowing you a greater strategic flexibility with respect of claiming the Level Taxes.
