Indeed, you can have a magic sword that counts as an arcane focus but it would be either in melee having no bonuses (meaning it counts as a magical weapon for DR bypassing but has +0 bonus otherwise) with bonus to spells attacks and save DC's, or count as an arcane focus but have +1 or more bonus.<br/><br/>My advice; if want to be a good caster but also good in melee, take separated focus and magic weapon because wizards have some damn excellent options for arcane focus which is not fused with a weapon. Arcane Grimoire (http://dnd5e.wikidot.com/wondrous-items:arcane-grimoire) counts arcane focus (adding +2 to spell save DC and rolls) and also spellbook (also a minor improvement on spell slot recovery in short rest). The only negative side is to need 'holding it' while casting. But you can get (or should get) Warcaster feat to able use your sword swings as somatic components for spells (besides other obvious benefits like an advantage to concentration rolls and use cantrip in opportunity attacks).<br/><br/>Then use another rare or legendary pick for the melee weapon that you using. The third attunement for any useful item you think makes sense for your char. But if not want to waste attunement for weapon, Dragon Slayer (http://dnd5e.wikidot.com/wondrous-items:dragon-slayer) has no attunement and can be any sword. It's +1 but has a solid extra function causing extra dmg vs draconic creatures. Also if allowed by GM you could flavor Bonecounter (http://dnd5e.wikidot.com/wondrous-items:bonecounter) as a sword than mace. There is Giantslayer (http://dnd5e.wikidot.com/wondrous-items:giant-slayer) (extra dmg and knocking foe prone if they giant type, +1), Serpent's Fang (http://dnd5e.wikidot.com/wondrous-items:serpent-s-fang) is +0 but provided always triggering +1d10 extra dmg (albeit poison which means fairly easy find enemies who resist it), Vicious Weapon (http://dnd5e.wikidot.com/wondrous-items:vicious-weapon) is magical and Weapon of Certain Death (http://dnd5e.wikidot.com/wondrous-items:weapon-of-certain-death) is also.<br/><br/>But can settle for +1 sword (uncommon) or +2 (rare) as a choice and both do not require attunement at all. Also spell component is fine solution as well, Xe'Nedra needs spell component cause arcane tricksters have no focus feature at all (would need multiclass as wizard to get it). But she gets by just pouch alone and having warlock side covered by her improved blade pact weapon functioning as focus for warlock spells.<br/><br/><div class="quoteheader"><div class="topslice_quote"><a href="https://elliquiy.com/forums/index.php?topic=349363.msg16417087#msg16417087">Quote from: Hatless on 03-03-2023, 16:42:59</a></div></div><blockquote class="bbc_standard_quote">Rules question though: am I overlooking something or do saves just never increase?

One solution can be taking Ring/Cloak of Protection to improve the saves a bit (and both items stack but ask attunement). I think glamerweave may function as underwear under the robe of the archmagi as the magical function could conjure through robes of archmagi.<br/><br/>
